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.Your limitation—it’s only your imagination.

It’s going to be hard, but hard does not mean impossible.The harder you work for something, the greater you’ll feel when you achieve it.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.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.

Great things never come from comfort zones.Great things never come from comfort zones.

Believe in yourself and all that you are. Know that there is something inside you that is greater than any obstacle.Don’t stop when you’re tired. Stop when you’re done.

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.
