Success is a journey, not a destination.

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. 

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

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

Dreams don't work unless you do.

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.

You cannot escape the responsibility of tomorrow by evading it today

Time is your friend, impulse is your enemy.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

Procrastination makes easy things hard and hard things harder.

It always seems impossible until it's done.

Your limitation - its only your imagination.

99% of genius comes from hard work, the remaining 1% comes from innate talent

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

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