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

Mathematics Is not a spectator sport. The only way to learn mathematics is to do mathematics.

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

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

The journey of a thousand miles begins with one step. 

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

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

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

Success can never happen without the journey (struggle).

You cannot start the next chapter of your life if you keep re-reading the last one.

Nobody said it’d be easy, they just promised it would be worth it.

A book a day keeps the stupidity away.

Tough times never last, but tough people do.

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