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

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.You don’t have to be great to start, but you have to start to be great.The only way to do great work is to love what you do.

Success is not final, failure is not fatal: It is the courage to continue that counts.The harder you work for something, the greater you’ll feel when you achieve it.

Don't wait. The time will never be just right.

Don’t stop when you’re tired. Stop when you’re done.Great things never come from comfort zones.

You don’t have to be great to start, but you have to start to be great.Don't wait. The time will never be just right.

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