In the midst of winter, I found there was, within me, an invincible summer.

Believe you can and you're halfway there.Success is not final, failure is not fatal: It is the courage to continue that counts.

The only way to do great work is to love what you do.The key to success is to focus on goals, not obstacles.Push yourself, because no one else is going to do it for you.

Don’t stop when you’re tired. Stop when you’re done.The key to success is to focus on goals, not obstacles.

You don’t have to be great to start, but you have to start to be great.

It’s going to be hard, but hard does not mean impossible.It’s going to be hard, but hard does not mean impossible.

It’s going to be hard, but hard does not mean impossible.Keep your face always toward the sunshine, and shadows will fall behind you.

It’s going to be hard, but hard does not mean impossible.The way to get started is to quit talking and begin doing.
