Part of the Ultimate Guide to Writing a Letter
Your envelope sits on the desk, blank and waiting, while your heart races with all the things you want to say.
We all want our letters to matter—to land in someone’s mailbox like a little gift of connection. Here’s the truth: the most common mistakes aren’t about grammar or fancy penmanship. They’re about the stories we tell ourselves that keep our pens from moving.

Let’s untangle these together.
Mistake 1: Waiting for the Perfect Moment
The biggest letter-killing mistake? Believing you need perfect conditions to write.
Perfect light. Perfect mood. Perfect words already lined up in your head. So you wait and wait. Meanwhile, your friend wonders if you’ve forgotten them.
Here’s what’s really happening: Your brain is protecting you from the risk of imperfection. Writing feels vulnerable, so it creates endless conditions that must be met first.
How to get past it: Write right now, in whatever state you’re in. Your messy first draft is infinitely better than the perfect letter that never gets written. Grab whatever paper is nearest. Tell your friend about your day, your dog, your thoughts. That’s enough.
Mistake 2: Trying to Sound Like Someone You’re Not
You sit down and suddenly your voice becomes formal. Fancy. Not at all like you.
“Dear esteemed correspondent: I hope this letter finds you in good health.” Stop. Your friend doesn’t want a stranger’s voice. They want your voice.
Why this happens: We think letters need to be “proper.” We imagine some invisible standard we should meet. So we write like we think we should instead of like we are.
How to get past it: Write like you talk. Use contractions. Start sentences with “And” or “But.” Use lowercase if you feel like it. Your authentic voice is what makes letters sing. Your friend already loves how you sound. Let them hear it.
Mistake 3: Overthinking Every Single Word
You write: “I’m so glad we can keep in touch.”
Then you pause. Is it too simple? Should it say “delighted” instead of “glad”? What if they think you don’t care because you didn’t use fancier language?
One sentence becomes five minutes of staring.
Why this happens: We confuse letter writing with formal writing. We think our words have to be impressive to be worthwhile. But letters aren’t about impressing; they’re about connecting.
How to get past it: Give yourself permission to be ordinary. The most moving letters I’ve received weren’t written by poets. They were written by people who simply said what they meant, simply meant what they said.
Mistake 4: Comparing Yourself to “Good Writers”
You’ve read beautiful and eloquent letters, letters that seem to flow like prose.
So you compare your rambling, honest letter to those polished pieces and think: I’m not a good writer.
And then you don’t send it.
Why this comparison trap exists: We see the final product but not the messy drafts, the crossed-out lines, the second-guessing. We think good letters just happen.
They don’t.
How to get past it: Remember that comparing your rough draft to someone else’s tenth revision is not fair play. Your letter is for your friend, not for publication. Your friend doesn’t need a “good writer”.
They need you.
Mistake 5: Writing Too Short (or Way Too Long)
You get nervous.
Maybe you write three sentences and panic: This is too short. They’ll think I don’t care. So you crumple it up.
Or you write four pages and worry: This is too long. I’m rambling. And back it goes.
What’s really going on: There’s no “right” letter length. A postcard can be perfect. A twenty-page letter can be perfect. Length isn’t the measure.
How to get past it: Write until you’ve said what you needed to say. Then stop. Your friend would rather have three genuine sentences than five pages of filler. Quality of presence matters far more than quantity of words.
Mistake 6: Not Sending Because It’s Not Perfect
This is the grief of letter writing.
The letter sits in a drawer. You keep editing it, adding to it. You’ll send it when it’s better, when you’ve found the right words, when you’ve said it exactly right.
Months pass.
Why this trap is so sticky: Perfectionism masquerades as care. It whispers that you’re protecting your friend from a mediocre letter. Really, you’re protecting yourself from being seen.
How to get past it: Send the imperfect letter. Your friend doesn’t need perfection. They need to hear from you. A messy, real letter beats a perfect one that never arrives.
Mistake 7: Losing Steam Mid-Letter
You start strong.
“So much has been happening! Let me tell you about…” and then somewhere around the second page, your energy drops. Your handwriting gets smaller. Your sentences get shorter. The letter trails off.
You finish it, but the ending feels rushed and thin.
Why momentum dies: You’ve said the big things. Now you’re not sure what else is worth saying. Writer’s fatigue sets in. You just want to be done.
How to get past it: Expect this dip and plan for it. When energy drops, that’s when you wrap up gracefully. You don’t need to fill every line. A strong, warm closing is worth more than padding. “Thinking of you! Can’t wait to hear what’s new with you” says plenty.
Mistake 8: Forgetting Your Return Address
You’ve poured your heart into this letter.
You seal it. You stamp it. You mail it.
And your friend can’t write back because there’s no return address on the envelope.
Why this happens: You’re focused on the letter itself, not the logistics. The envelope feels like an afterthought. So it gets treated like one.
How to get past it: Make it a ritual. Before you even touch the letter, write your return address on the envelope. Or make a small sticky label with your name and address that you place on every envelope you send. One tiny habit prevents this common heartbreak.
Mistake 9: Getting Stuck on How to Sign Off
“Sincerely” feels too stiff. “Love” feels too big. “Your friend” feels silly. “XOXO” feels not like you.
You’ve written a whole letter and now you’re paralyzed by the final three words.
What’s happening: You’re treating the sign-off like it’s more important than the letter itself. It’s not. It’s just the ribbon on the gift.
How to get past it: Use what feels true to you. “Warmly.” “Always.” “Thinking of you.” “Can’t wait to catch up.” You could even sign off differently each time. There’s no wrong way, only the way that’s authentic to you and your friendship.
Mistake 10: Procrastinating on Replies
Your friend’s letter arrives and it’s wonderful.
You mean to write back. You will. You just need to find the time. The right stationery. The right moment.
Two weeks become two months. You feel so guilty now that replying feels harder.
Why this spiral happens: The longer you wait, the bigger the reply feels. What started as “I’ll write this weekend” becomes “I owe them this amazing response now.” Guilt makes the blank page heavier.
How to get past it: Reply sooner, even if it’s just a postcard. Say, “Your letter made my day and I’m writing a real reply this weekend.” Then actually do it. Momentum is real. The sooner you write back, the easier it feels.
Letter-Writing Mistakes FAQ
Q: What if I make a mistake while writing? Can I cross it out?
A: Yes! Crossed-out words are honest. They show you were real and present while writing. Your friend will read right past a single strikethrough and see the heart of your letter. Perfection is cold. Humanity is warm.
Q: How do I know if my letter is interesting enough to send?
A: If you felt something while writing it—joy, vulnerability, connection—then it’s interesting. Letters aren’t about having an exciting life. They’re about sharing what’s real with someone who cares about you. Your everyday moments are gold.
Q: I haven’t written someone back in months. Is it too late?
A: Never. Write now! Acknowledge the time that’s passed if you want to (“I can’t believe it’s been three months!”), and then just pick up the thread. Most people are thrilled to hear from you, regardless of how long it’s been. Overdue connection is still connection.
Q: Should I worry about my handwriting?
A: Only if it’s illegible. Messy handwriting is character. It’s proof a human held a pen and thought of someone. That matters infinitely more than pristine cursive. Your friend will treasure a rambling, messy letter from you far more than a perfect typed one.
