To me the most important element of cooking is never giving up on yourself and what you are capable of. Not even the top chefs in world succeed everytime. Sometimes it may take multiples failures (I like to call them carry out nights) to get the dish where you want it to be.

Through each of those failures is a chance to step back, mentally replay the dish, and learn something that will carry you forward.

That lesson could be something as simple as create a slurry instead of throwing the cornstarch into the sauce you want to thicken to write down your entire step process before starting the dish to avoid missing a crucial step.
