The last 5 years I did around 75 hour weeks (salary so no OT) but i could do it from home when I wanted. Now its normalized again since our company was bought, so I'm closer to 40 hrs now, feels much better.
I go into the office 4 days a week (mon - thu), maybe 6 hours a day (9 to 3). (24 hours) the rest I do from home. (Firewall migrations in remote locations, etc)...
Then it's off to the gym when Im done for the day, which is only a few steps away from my home office out in my garage.
House and 5 cars paid off (family of 4 plus my extra truck for plowing, etc) , so no debt, just paying for 2 kids in college (without taking loans)...
In 5 years when I'm 53, I'll start winding it down (after kids graduate). 30 years of 401K's with employer matching has really built up over the years for retirement...
Maybe I'll go do the 4 hr. a day UPS thing, just for their insane benefits and the exercise...
