Journal: write a letter to yourself as a teen/child

One important thing in knowing yourself is to be able to look back at your past and recognize mistakes you've made and also times when you made good decisions. Write a letter to yourself as a teen or child and give yourself some advice for "the future." You'll probably find that the advice you give your younger self is good advice to follow right now! You've definitely changed in the years since you were younger, but as they say, if you don't learn from history, you're doomed to repeat it!
