Good advice no one ever told me:
Halloween isn't fun when you are the person carving the pumpkin, buying the candy and enduring the constant pleas of "How much longer until we can trick or treat?"
If you are in your 20's, STD free and unattached - and are of the inclination - you should have protected sex with whomever you chose. Really. I look at these young beautiful women and think about how much time I worried about my "reputation", et al. What the hell was I saving myself for?
Don't bother to fake an orgasm - I mean, honestly. It does nothing for you, and gives your partner zero feedback. If they are doing something that isn't working for you, speak up. In fact, don't fake anything.
TB's adds: Go naked more often, which I agree with whole heartedly
Buy and wear the pretty underwear. For yourself.
Young men in their 20's are idiots. I also look at them and am astounded that anyone finds them charming or attractive. I certainly do not. (I qualify this by saying that they are "cute", certainly. However, having watched them close up for two years now, and seeing these lovely young women look at them adoringly....Sigh. Kind of makes me want to shake them. The same feeling I had when I saw pre-kids, pre-crazy Brit and K-fed, and I wanted to grab her and say "NO!!!!!")If you are in love with one of these men, know that they will not change (see Lisa's Comment). What you see is what you get later on. But with Hair growing out of odd places.
There may come a moment when you think "My partner actually understands me!" and you will be grateful. This moment, of course, may pass. It will come back again, you just can't know when.
Other peoples babies are very cute. Your baby will be the most work/worry/lack of sleep/joy you never imagined. Proceed with caution.
There is nothing more pleasurable than laying in bed in the sunshine. Adding coffee ups the pleasure even more.
Parking in a city engenders a certain ruthless attitude.
Eat what you want.
Reading graphic novels as an adult is really fun.
Spending money on music is never wasted. Yes, you may regret some of the CD's in hindsight (Yes Slow Jams CD I am talking about you)
Drink the wine you like.
You will come to enjoy the joy of someone else cooking for you. When your parent did it, I mean - it was no big deal. If you have had to do it for yourself, you will be wildly grateful for a nice bowl of soup made by someone else.
There will come a day when you weigh - heavily - the two to three days of being hungover for the one evening of drunken debauchery.
Hit me with your wisdom, my loves.
