When I first opened my business, I was a one man show. For the first 18 months, I did not take one day off. Not sundays, not holidays, not Christmas (half day). Most days started about 6 am and ended at 9, but many were 20hrs, 4-12. Typical workweek was 80-100 hours.
The secret to doing this was to be married to a woman who made my life a living he11 when she was around. Hate can move mountains.
15 years later I work 5 days a week, maybe 40 hours, and I'm married to a wonderful lady who shares my interests.
If anyone feels to need to work ridiculous hours, I'll see if I can find the phone # of my ex-wife.
