I don't want to sh1t on anyone's parade, but where in this timeframe do you have time to be a well-adjusted person with friends and a family?
M-F: 8am-8pm. Home by 8:30, eat till 9pm. Take a shower. Assuming you'd like 8 hours of sleep, you have a whole one hour of free time per day assuming you wake up at 7am.
Saturday: 8am-6pm. Hopefully you won't be too drained from a 10 hour day to go out at night.
So you've basically got one day a week to sleep in, and 1 day off. And that's a 70 hour week. I've never heard of a 40 hour week, but I've heard of a 90 hour week, so I'd say 70 is about average at those places. Good luck with that
