Building software makes me happy. I understand lying in a cave with a PC for 80 years isn't smart and that's not what I'm suggesting (if your statement implies this). I'm also not saying this is a single variable that guides my decision making process around how I use my time (or how others should). But it's different to how I'd feel if I hated my job and some brogrammer on linkedin suggested grinding is the way to go as money = bit*es.
