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

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

It’s going to be hard, but hard does not mean impossible.Keep your face always toward the sunshine, and shadows will fall behind you.The greatest glory in living lies not in never falling, but in rising every time we fall.

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

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.Great things never come from comfort zones.

Great things never come from comfort zones.The harder you work for something, the greater you’ll feel when you achieve it.

The only way to do great work is to love what you do.Dream it. Wish it. Do it.
