The Dalai Lama, when asked what surprised him the most about humanity, he answered" man. Because he sacrifices his health in order to make money. Then he sacrifices money to recuperate his health. And then he is so anxious about the future that he does not enjoy the present; The result being that he does not live in the present or the future; he lives as if he is never going to die, and then dies having never really lived."
With that being said. Don't work too hard guys. Leave spare time for the things you love, the people you love and some good exercise.
I put my health off for awhile trying to push forward. I have come a long way since then.
I used to work 16 hour days, leave the house once a month because I was going to MAKE IT!
Then I saw lack of production.
I eventually learned that having a set schedule and only working 8 hours a day was best.
You push yourself harder during that time frame and it sounds like it wouldn't help but it actually does.
Don't strain yourself. Enjoy life.
