Dear 12 year-old me,
Stop looking forward to the day when you'll finally be a grown up. Sure, being a grown up means that you can stay up as late as you want, that you can drive, and that you will be completely in control of your own life. However, when that time comes, you'll come to LOVE sleeping and going to bed early and you'll hardly ever get to drive your own car because you have to share it with your husband. Being grown up is overrated. Big time. Just be a kid.
Love, 25 year-old you.
