Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

The bad news is time flies, the good new is that you're the pilot.

Don't expect to be good at maths or understand things straight away. Be patient and persistent. Rome wasn't built in a day, but they worked on it every single day. 

Success is a journey, not a destination.

Everything you want is on the other side of fear

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

I have not failed, I've just found 10,000 ways that won't work.

Success is not final, failure is not fatal.  It is the courage to continue that counts.

It doesn’t matter where you start, it matters how you end

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

Don’t compare yourself to others. Compare yourself to the person you were yesterday.

Don’t hang your targets after you’re done shooting.
