“Strive to be better today than you were yesterday.”

“It's not that some people have willpower and some don't... It's that some people are ready to change and others are not.”

“Do not dwell upon the sins and mistakes of yesterday so exclusively as to have no energy and mind left for living rightly today, and do not think that the sins of yesterday can prevent you from living purely today.”

“If you're talking about what you did yesterday, you're not doing much today.”

“Nothing in life is more exciting and rewarding than the sudden flash of insight that leaves you a changed person, not only changed, but for the better”

“If today you are a little bit better than you were yesterday, then that's enough. And, if tomorrow you are a little bit better than you were today, then that's enough.”

“Live today as if you were going to live forever, for you surely shall.”
