I would tell myself:
1. Start putting money in your 401K right now.
2. Start putting money in a savings account right now.
3. NO CREDIT CARDS.
4. You are so cute right now.
5. Take care of yourself. Go run up and down the stairs three times RIGHT NOW!
6. Forget about the stupid birth control.
7. Throw the diary away.
8. Jeremy loves you a whole lot, you really do mean the world to him.
9. That money you are putting in savings should be used for a fabulous honeymoon.
10. After the honeymonn the money in savings shouldn't be touched but for emergencies and maybe a really great down payment on a new house.
11. NO CREDIT CARDS...I mean it!
