When I am cooking, I have trained myself to set a timer for 10 minutes.

My rule for cooking is "don't leave the kitchen", but that isn't realistic. I wander without realizing. It's an issue. I've been in another room and the timer has gone off and I'm like,"Oh fuck!". I completely spaced it.

Anyway, when the timer goes, I set another timer for 10 minutes. Rinse and repeat until the stove is off.
