i used to do those hours when i was your age.Busy as ever but somehow managing my stress insanely well!
In the lab M-F in the morning and then bartending 4 nights a week 5-10pm.
So I only have 1 full day off a week if im lucky and work 14 hour days ~3 days a week. But my mentality couldnt be better!
How's everyone else???
good news.
you will survive.
