Don’t think of the weekend as the time to take off. Quit thinking of your life in terms of a M-F 8-5 lifestyle. Start doing things you love more and you won’t care what day of the week or what hour of the day it is. Sunday will feel like Tuesday, and you won’t care if it is 3am or 6pm.
Do more of what you love. And live 7 days a week. I could be wrong, but that seems like a pretty awesome way to live.
