“Tomorrow owes you the sum of your yesterdays. No more than that. And no less.”

“Remember this your lifetime through:
Tomorrow there will be more to do.
And failure waits for all who stay
With some success made yesterday.
Tomorrow you must try once more,
And even harder than before.”

“Me and you, we got more yesterday than anybody. We need some kind of tomorrow.”

“You live your life today,
Not tomorrow,
and certainly not yesterday.”

“Never regret yesterday. Life is in you today, and you make your tomorrow.”

“It's all now you see: tomorrow began yesterday and yesterday won't be over until tomorrow.”

“All economic activity is by definition "high risk." And defending yesterday--that is, not innovating--is far more risky than making tomorrow.”

“Live today. Not yesterday. Not tomorrow. Just today. Inhabit your moments. Don't rent them out to tomorrow.”

“Being attached to the problems of yesterday or the insecurities of tomorrow will destroy your today.”

“Today is the tomorrow you were promised yesterday.”
