30 things I wish I knew about dating when I was 21

I'm still having a hard time following this advice today, putting it in writing is a good way to cultivate these good habits...

1.  Sometimes what you think is love is really loving the moment and the way this person makes you feel [for the moment].
2.  Before marriage men really talk a big game about marriage, turn a deaf ear.
3.  Know who you are, and what you want, the rest will come to you.
4.  "Don't go for second best baby, put your love to the test" Madonna.
5.  You can't fix him.  Never stay with someone hoping they'll change. You can only change you.
6.  Stop giving in hopes of getting.
7.  Don't force chemistry.
8.  Be single and enjoy it.
9.  Not every boyfriend is marriage material.
10. Giving too much of yourself, gifts, favors, etc. makes you seem needy.  Even if it's just your nature, give too much to your friends not to him, it cultivates baaad habits.
11. Expectations will always lead to disappointment.
12. Know your standards, but be realistic.  Stick to your guns.
13. If you feel a crazy outburst coming on or the need to talk endlessly about a topic, breathe and walk away.
14. Never hit a man, if it's okay for you to resort to physical violence then it's not okay for him.
15. If your confused about the relationship, leave...
16. Do not make idle threats.
17. If you ask a question, know beforehand that the answer you get may not be the one you want and prepare for it.
18. Don't give in to societal pressures and labels, if a man can have sex just because he wants to, then so can you.
19. Always listen to your gut (sometimes its a really really really hard thing to do).
20. Be strong, don't give in to your weaknesses.
21. Know that everything will work itself on in the end.
22. Don't be with a pot-head.
23. Have your own hobbies, spend time apart with your own friends.
24. You may think opposites attract...but not for long.  You must have core similarities.
25. Don't pay too much attention to what other people think, but sometimes you do have to listen if everyone is saying the same thing.
26. Money does matter in a relationship.  But potential and drive should matter more.
27. Know the meaning of compromise...it has to be mutual.
28. You'll know from the first kiss.
29. Don't be scared of being alone/lonely.
30. There are more women than there are men, so if things never work out in love, it's just a numbers game!
