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. 

99% of genius comes from hard work, the remaining 1% comes from innate talent

Dreams don't work unless you do.

No one starts out on top. You have to work your way up.

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

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

You're not in competition with anyone but yourself. Outdo your past, not other people.

Don’t confuse your path with your destination. Just because its stormy now doesn’t mean you are headed for failure.

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

Hard work beats talent when talent doesn't work hard.

Success is not final and failure is not fatal. It is the courage to continue that counts.

Time is your friend, impulse is your enemy.

A book a day keeps the stupidity away.

Success can never happen without the journey (struggle).

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