> They're not going to live in cardboard boxes.Maybe not, but I've seen quite a few indies with massive debt, and who are struggling with depression & anxiety as a result, and that's huge pressure on their family. Which makes keeping the family together an added anxiety, and then it's a vicious cycle. [It echoes the Phil Fish line from Indie Game: The Movie about wanting to kill himself.]
Burning yourself out on making a game (or a startup, or anything) is not worth that. Family and general happiness is so important. Keep things in scope so that if the lottery ticket doesn't work out, you've still got things to fall back on.
