Oh cool, so basically this is about finding a way to cheat your brain into doing things it doesn't want to do. Maybe a good approach would be to find something you actually like to do instead and reflect on your choices and priorities in life?
It's amusing that you need a professor to tell you how to convince yourself that your life doesn't suck. A more natural approach might be to change what you are trying to do in the first place...
Guess what, the brain was not made to earn money.
