I am so glad you posted this!
I already enjoy 3 of these (drink, sex, credit card) and I sometimes feel guilty because they may adversely affect my work. Starting immediately I'm adding the other 4 and I'm not going to feel guilty about any of them.
A friend of mine offered me a real Cuban cigar yesterday and I politely refused. I'm calling him back tonight. I'm also going to the mall and buying something I never would have worn before. Then I'm hitting the casino and I don't care if I win or lose. I'll skip the oysters, but Saturday night, I'm picking the most decadent thing on the menu. And yes, there will be beer (maybe even spirits) and sex.
If Hemingway, Einstein, Churchill, Mark Twain, and Oscar Wilde indulged to feed their creativity, then maybe I should do it more often, too. I'll let you all know how it goes. A couple of days later.
