How to cook

When I talk to people who don't cook I often find myself saying something ridiculous like, "Cooking is easy, it's mostly just paying attention to what you're doing."  Which I really think is true but is just about the most unhelpful statement you can make.  It got me wondering if I could come up with a formula for cooking, breaking it down into its parts, 10% this and 33% that.  So here is my list and percentages:

shopping 35%
     you can't make good food with bad ingredients
technique 15%
     it's easy to destroy good ingredients if you don't treat them right
history/knowledge/context/experience 5%
     mostly avoiding past mistakes or building on past successes
creativity 5%
     I think often over-rated in American culinary culture, the quest for the next new thing leads to more bad food...
patience 15%
     knowing when not to mess with it, waiting until summer for strawberries
paying attention 25 %
     cooking is an interactive and dynamic process

What do you think, would you assign different percentages or different elements?
