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

There is no elevator to success, you have to take the stairs.

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

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

If you want to succeed, double your failure rate.

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

Pure mathematics is in its way, the poetry of logical ideas.

Time is your friend, impulse is your enemy.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

Your limitation - its only your imagination.

When you make a mistake, take another chance. Only when you choose not to do so do you fail.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

Go as far as you can see, when you get there, you’ll be able to see further

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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