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

It’s going to be hard, but hard does not mean impossible.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.The harder you work for something, the greater you’ll feel when you achieve it.Wake up with determination. Go to bed with satisfaction.

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

The key to success is to focus on goals, not obstacles.

Keep your face always toward the sunshine, and shadows will fall behind you.You don’t have to be great to start, but you have to start to be great.

Believe you can and you're halfway there.Don't wait. The time will never be just right.

Keep your face always toward the sunshine, and shadows will fall behind you.Keep your face always toward the sunshine, and shadows will fall behind you.
