“If you're talking about what you did yesterday, you're not doing much today.”
“Don't ever let your mistakes hold you back & define your life. It's not what you did yesterday but what you're doing today. Humanity needs diligent workers to help better brighten our world!✌”
“If what you did yesterday still looks big to you, you haven't done much today.”
“If you realize you aren't so wise today as you thought you were yesterday, you're wiser today.”
“Don't worry about what you did yesterday, he said, often, worry about what you haven't done today.”
“Remember, lad," said the newt, "If it's going to be tommorow, it might as well be today. And if it is today, it could have been yesterday. If it was yesterday, then you're over and done with it, and can write your own book. Think about that.”
