I wish everyone understood this. I wish a younger me understood this. I did the start up grind and then did my own company for years before it ultimately failed. I was working massive hours and had incredible stress towards the end. Far too late, I learned that it was killing me. I now have a low stress job that pays well but I have extremely high blood pressure and a host of related co-morbidities - and I'm only in my mid-40s. I've become quite obsessed with ensuring a good future for my family first and ideally retiring early and traveling because I just cant see myself making it into my 60s at this rate.
