Hey mark it’s great to see you here and I agree with what you say about the terms like Crush It and Hustle. I prefer just do well and work hard.
As to the point of this post I believe the OP is missing the point. I wrote my second book by working after my 9–5, sometimes until 2am and sometimes I’d start at 3am, and I was usually mad when I was tired because I wanted to continue working.
After writing the book I then opened a franchise business while keeping my day job. That was a lot of work, again spending time at the business long after closing and going in long before opening to set things up.
Did I suffer? Yes, but I was doing what I wanted to do. I was working hard to reach a goal. It caused strain but I have gotten so much out of it. Taking that time and sacrificing what I did means I no longer need my day job any more.
Each person has to determine how much they can put into something. Gary has never said you have to do it the way he did and I’m not saying you need to do what I have done but simply dismissing his advice as unhealthy is silly.
