This is the wrong model:
Sitting (alone) at home and working on program code or reading scientific textbooks does have a reward. Many things for which you go outside of the house or where you interact with other people have a much lower reward. So you rather loose a rather decent local optimum, and if you don't know very well where to look outside for something really good, you get much worse results than if you simply stayed at home and do there what you love.
