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

Everything you want is on the other side of fear

Success is a journey, not a destination.

The journey of a thousand miles begins with one step. 

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

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

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

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

It doesn’t matter where you start, it matters how you end

Time is your friend, impulse is your enemy.

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

The master has failed more times than the beginner has even tried

I think, therefore I am.

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. 

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