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.

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

You cannot escape the responsibility of tomorrow by evading it today

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

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

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

Hard work - a two way street where you get exactly what you put in.

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

Focus on progress, not perfection. Practise a little bit every day - little and often  Slow and steady wins the race.

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

I can is 100 times more important than IQ.

Failure to prepare = preparing to fail

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

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.
