I’ve seen this sentiment paraphrased in one way or another many times, in many different places. The gist is this:
“The cost of success is tons of hours of work, no social life, sacrificing your health & sleep, skipping family events, and putting all your money back into your work – if you’re not willing to do that, you won’t succeed.”
I mean… I can imagine something being worth that. If I truly believed that doing all that would cure cancer, I’d be morally obligated to do it. But for just “personal success?” I mean – if you don’t have any of those other things, what does “success” even mean?
