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

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. 

It is never too late to turn an unproductive day into a productive one.

If you fail, next time fail better.

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.

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

Nobody said it’d be easy, they just promised it would be worth it.

Everything you want is on the other side of fear

A book a day keeps the stupidity away.

There are no shortcuts to any place worth going.

The wise person knows that no answer is also an answer

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

No matter how bad it gets, you’re still way ahead of those who haven’t even started.
