Right now, I've got pretty much every Michael Chiarello cookbook my library would let me take out at once, and I found something fun that I thought I'd share.
In the front of "Flavored Oils: 50 Recipes For Cooking With Infused Oils", he offers his "rules for cooking". They are:
1)Don't cook if you don't want to.
2)Don't cook when you are full.
3)Shop when you are hungry.
4)Cook with the ingredients in the biggest displays. This is usually produce at the peak of its season.
5)Make the food your own - substitute and experiment - just never say "I can't make that because I don't have that exact ingredient."
I like number four. It makes total sense, but who thinks of that? I never had.
