How many minutes again?

I'm a lazy cook. Now, I know that won't come as much of a surprise considering that half my posts in this blog are about how I'm lazy all the time. But, I actually think I have the potential to be a great cook. My dishes would taste so much better if only I chopped the onions more finely, waited five minutes more. Things like that. The thing is...when I look at a recipe and see, 15 minutes, I'm like, this tastes fine even at the 10 minute mark. So, I stop cooking.
The problem is that I cook when I'm hungry. And, when I'm hungry, I want to eat something immediately. Therefore, the coarsely chopped vegetables, less time and stuff.

I suppose this means that I should cook with a full stomach.

Yeah, no, where's the motivation then?
