I have one thing: Do everything you can do NOW. I should have done all those things, I went "*tsk* Should I do this? Should I do this?" To hell with it! Do it! You can always look back and go "I shouldn't have done that!"
I heard this while getting ready for work this morning listening to the Farewell Tour on the iPod. We should always listen to Cher. Whenever you find yourself wondering what you should do, just ponder this T-shirt.And then do it.
What a wise woman.
