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. 

FAIL - First Attempt In Learning

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

There are no shortcuts to any place worth going.

The road to success is like a staircase. If you want to succeed, double your failure rate

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

The greatest enemy to human potential is your comfort zone

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

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

Time is your friend, impulse is your enemy.

I can is 100 times more important than IQ.

You cannot escape the responsibility of tomorrow by evading it today

Never underestimate the importance of small steps. small steps = big changes. 

Success is a journey, not a destination.
