Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

It is never too late to turn an unproductive day into a productive one.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

It always seems impossible until it's done.

Tomorrow is worth more than yesterday but less than today.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

Instead of finding reasons why you can't, find reasons why you can.

If you can understand just one thing thoroughly, then you will understand everything.

Don’t practice until you get it right, practice until you can’t get it wrong.

99% of failures come from people who have the habit of making excuses.

He who has begun his task is half-way done. Have the courage to begin!
