If you're going to hustle that hard then also make sure to eat well and to look after yourself.

I worked hard but did not take care of myself and ate a lot of things that were not good for me. Almost died just before my 60th birthday from a heart attack. I said I'm done and retired, and am concentrating on my health and my wonderful wife and kids. Quit smoking, started eating very clean and I'm in the gym 5-6 days a week with my wife and we're both enjoying my retirement.
