> Don't listen to PG, kids. Live the life you want to have now, not the life you think you'll want to have several decades out. It really depends on what you're working for. If your goal is retire in 50s that's pretty achievable without working terribly hard (for most engineers). If your goal is to be as good at soccer as Lionel Messi probably not so much. Define what your goals are really well, then you can figure out what level of work is required to get there, then decide if that's a sacrifice worth making to you or if you want to adjust your goals. Of course, there's some unknown in there, but if you don't want to be incredibly rich and change the world it doesn't take the same inputs.
