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

We all make mistakes. What matters is how we choose to move forwards from them.

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

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

Dreams don't work unless you do.

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

Fall down seven times, stand up eight.

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.

There are no bad mistakes in maths, only discoveries.

I think, therefore I am.

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

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

Procrastination makes easy things hard and hard things harder.

The greatest mistake we make is living in constant fear that we will make one.

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