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

Believe you can and you're halfway there.The harder you work for something, the greater you’ll feel when you achieve it.

Great things never come from comfort zones.Don’t stop when you’re tired. Stop when you’re done.In the midst of winter, I found there was, within me, an invincible summer.

Great things never come from comfort zones.Push yourself, because no one else is going to do it for you.

The greatest glory in living lies not in never falling, but in rising every time we fall.

Push yourself, because no one else is going to do it for you.Your limitation—it’s only your imagination.

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.

The only way to do great work is to love what you do.The way to get started is to quit talking and begin doing.
