1. People eat more than one helping of it.
2. Whatever it is, it doesn't rust.
3. You might not know that you're good at it. In fact, it's probably best if you don't know how good you are at it.
4. It feels natural, graceful, full of ease. (or) It's difficult, you don't get it right sometimes, you wish you could trade it in for something else, something easy, safe, repetitive like putting the plastic wrap around fortune cookies rather than coming up with the actual fortunes.
5. Some days it takes a team of wild horses to get you back to doing it. Many times you try to bribe the horses with apples and honey-covered carrots, but they don't fall for the sweet stuff until you've done your work.
6. You struggle with it. You talk to it. It talks back. You have opinions. It has opinions. You continue to work together because you both need each other--sometimes more than water or air or food.
7. You lose sleep over it, but you never feel tired.
8. It no longer matters to you if you're good at it. You just do it.
