Try learning something new. Learn to cook. You will get frustrated by some aspect of it. Then your laziness will spit out something like 'someone should make A so that people like me don't have to do X,Y and Z'

My example. I'm trying to save money and learn to cook, so I wanted a 3d plot of recipes on the axis of (Money/Calorie), (Time), and Rating. Then I could just look at a graph and know what to cook.
