You'll make it work. Believe me, you'll sort out a somewhat decent work/life balance. It'll just take time to get used to the routine. But once you do, expect a HUGE increase in time efficiency your end. With a seven day week you can kiss procrastination goodbye. You'll be on it like a car bonnet, trust me.
Saturday I was milking cows at 4 am. I then worked through to the afternoon and jumped on the train to London. I may have been there until nearly midnight, and I may have only slept three hours at most, but I was determined to get away and do my thing regardless.
The term 'sleep when you're dead' sort of springs to mind. I've got one shot at life, and I'm going to live it.
