The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

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

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

The easiest person to deceive is yourself.

It always seems impossible until it's done.

You can have results or excuses, not both

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

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Try and do one thing each day that you would really rather not do.

Go as far as you can see, when you get there, you’ll be able to see further

The wise person knows that no answer is also an answer

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

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.
