The questions you should ask yourself:
1. How willing are you to keep on solving a problem? How do you react when the first five or ten times you have a problem, your solutions don't work?
2. How good are you at writing extremely detailed instructions? A good check: Write your favorite recipe, give it to a friend, and ask them to cook it. Afterward, ask them how difficult it was to cook. (This test is EXTREMELY valuable when your friend says that they don't know how to cook.)
3. How do you react when you work very, very hard on something -- then someone who has never touched it says someone else "could have done it in five minutes"?
4. How do you react when something that you've studied and practiced for five years goes out of fashion?
