Quote by Roy Baumeister

"The self is not a thing but a process. It is something you do, not something you have."

"One of the most universal cravings of our time is a quality of identity and allegiance."

"Willpower is like a muscle. The more you use it, the stronger it gets."

"Self-control is strength. Calmness is mastery. You have to get to a point where your mood doesn't affect your productivity."

"Perseverance is the key to success."

"Don't give up on what you believe in."

"I've been through worse."

"You learn to live with the pain."
