Ehh for the past month I have been slacking a bit, but between school and work I'm used to putting in 12-18 hour days 5-7 days a week. Such is life, but man once I get out of school and only work like 50ish hours a week, its going to feel like vacation!
I forget who said this but I like this saying a lot. "You should only work half a day, whether its the first 12 hours or the second is up to you."
