Whenever you find yourself doubting how far you can go, just remember how far you have come.

Success can never happen without the journey (struggle).

Do what you have always done and you will always be what you have always been

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Failure to prepare = preparing to fail

Don’t be afraid to work hard and find out how good you can really be.

Success is a journey, not a destination.

We learn more from failure than we do from success.

Shoot for the moon and even if you miss you’ll land among the stars/

Dreams don't work unless you do.

If you can understand just one thing thoroughly, then you will understand everything.

A hero is no braver than an ordinary man, but he is braver five minutes longer.

Don't fear failure, fear being in the same exact same place next year as you are now.

Never underestimate the importance of small steps. small steps = big changes. 

Just stick with it, what seems hard now will one day be your warm up.
