Great things never come from comfort zones.

The harder you work for something, the greater you’ll feel when you achieve it.Your limitation—it’s only your imagination.

Don’t stop when you’re tired. Stop when you’re done.The key to success is to focus on goals, not obstacles.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.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.

Believe you can and you're halfway there.Push yourself, because no one else is going to do it for you.

The harder you work for something, the greater you’ll feel when you achieve it.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.Don’t stop when you’re tired. Stop when you’re done.
