Failure to prepare = preparing to fail

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

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. 

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

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

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.

I think, therefore I am.

Run in the morning before your body figures out what you're doing

Dreams don't work unless you do.

The greatest glory in loving lies not in never falling, but in rising every time we fall.

There are no bad mistakes in maths, only discoveries.

We learn more from failure than we do from success.

Everything you want is on the other side of fear

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