Don’t stop when you’re tired. Stop when you’re done.

In the midst of winter, I found there was, within me, an invincible summer.Success is not final, failure is not fatal: It is the courage to continue that counts.

You don’t have to be great to start, but you have to start to be great.The way to get started is to quit talking and begin doing.Keep your face always toward the sunshine, and shadows will fall behind you.

Wake up with determination. Go to bed with satisfaction.Your limitation—it’s only your imagination.

Great things never come from comfort zones.

The greatest glory in living lies not in never falling, but in rising every time we fall.Push yourself, because no one else is going to do it for you.

The way to get started is to quit talking and begin doing.Push yourself, because no one else is going to do it for you.

Believe you can and you're halfway there.It’s going to be hard, but hard does not mean impossible.
