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

The temptation to quit will be the greatest when you are about to succeed

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

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

Your attitude is everything. Pick a good one.

Nothing is impossible if you want it badly enough. Impossible = I'm possible.

We all make mistakes. What matters is how we choose to move forwards from them.

Failure to prepare = preparing to fail

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.

There are no shortcuts to any place worth going.

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

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

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