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

It is never too late to become what you might have been

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

Never underestimate the importance of small steps. small steps = big changes. 

Knowledge is of no value unless you put it into practice.

Tough times never last, but tough people do.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

Everything you want is on the other side of fear

There are no shortcuts to any place worth going.

Don't fear failure, fear being in the same exact same place next year as you are now.

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. 

Just stick with it, what seems hard now will one day be your warm up.

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

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

Fall down seven times, stand up eight.
