we have to stop thinking exploiting ourselves for someone else's gain makes us a better person.
i'm not saying the author says the opposite, but i think in any discussion of hard work we need to bring up balance. a good part of Bill Gates success was the money infusion from his friends and a wildly asymmetrical deal with IBM and the writer of DOS on the other side.
if we don't take a more nuanced approach we are (intentionally or not) perpetuating the myth of sacrificing your life for your company. i did that with my 20s and a chunk of my 30s. would not recommend. live your life, you only get one trip through and sometimes the body doesn't hold up well enough to keep enjoying all the things you love.
