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. 

Don’t practice until you get it right, practice until you can’t get it wrong.

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

Everything that happens was once a dream.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Life is full of opportunities. With every opportunity that is missed, another one is born.

No one starts out on top. You have to work your way up.

I think, therefore I am.

Failure is not the opposite of success, it is part of the success.

You can pick up a mistake and carry it as a burden,  or you can set it down as use it as a stepping stone to greatness.

The power of reflection is the most powerful skill you’ll learn.

There are no shortcuts to any place worth going.

You cannot escape the responsibility of tomorrow by evading it today
