The key to success is to focus on goals, not obstacles.Don’t stop when you’re tired. Stop when you’re done.Great things never come from comfort zones.

The key to success is to focus on goals, not obstacles.Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.

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

Keep your face always toward the sunshine, and shadows will fall behind you.Don't wait. The time will never be just right.

Do something today that your future self will thank you for.It’s going to be hard, but hard does not mean impossible.

You don’t have to be great to start, but you have to start to be great.Success is not final, failure is not fatal: It is the courage to continue that counts.
