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

There are no bad mistakes in maths, only discoveries.

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

We learn more from failure than we do from success.

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

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. 

Tough times never last, but tough people do.

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

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

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

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

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

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

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

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.
