What to Write in a 21st Birthday Card

You read every 21st birthday card in the Hallmark store, and that took what felt like ten years off your life. Now, when adding a personal note you’re stuck with writer’s block?!

Don’t worry – whether you want to go silly and funny, sweet and sentimental, or something in between, we’ve got plenty of ideas to get your pen flowing smoothly.

The main thing is to hit the high notes. Here are some things to consider including in your birthday message:

  • Remember the good times spent together
  • Express high hopes for the future of your relationship
  • Offer wisdom that you’ve gleaned from your years
  • Give encouragement in the next stage of their journey
  • Use humor or tell a joke to validate the joy of the relationship you share
  • Share a quote or Scripture verse
  • Tell them what they mean to you

It’s that last one that will mean the most to the recipient. Far too little do we tell people the impact they’ve had on our lives, compliment them, and express our love and appreciation. Use this birthday as an opportunity to do that!

So here we go: 100 bits of inspiration to help you fill out that card with the perfect 21st birthday message.

You’re only getting started! Best wishes and lots of love on this, your 21st birthday!
