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

If you can understand just one thing thoroughly, then you will understand everything.

Failure to prepare = preparing to fail

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

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

Try and do one thing each day that you would really rather not do.

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

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

Mistakes have the power to turn you into something better than you were before.

Your limitation - its only your imagination.

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

I have not failed, I've just found 10,000 ways that won't work.

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 bad mistakes in maths, only discoveries.
