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

The harder you work for something, the greater you’ll feel when you achieve it.Keep your face always toward the sunshine, and shadows will fall behind you.

Don't wait. The time will never be just right.The greatest glory in living lies not in never falling, but in rising every time we fall.The way to get started is to quit talking and begin doing.

In the midst of winter, I found there was, within me, an invincible summer.Don’t stop when you’re tired. Stop when you’re done.

Push yourself, because no one else is going to do it for you.

The only way to do great work is to love what you do.Your limitation—it’s only your imagination.

Don't wait. The time will never be just right.Success is not final, failure is not fatal: It is the courage to continue that counts.

The way to get started is to quit talking and begin doing.Don't wait. The time will never be just right.
