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. 

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

You'll never change your life until you change something you do daily. The secret to success and change in found in your daily routine.

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

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

Skills are built not born.

I think, therefore I am.

Tough times never last, but tough people do.

Failure to prepare = preparing to fail

1.00³⁶⁵=1 and 1.01³⁶⁵=37.7. Doing nothing at all versus small steps at a time. 

Everything you want is on the other side of fear

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

I can is 100 times more important than IQ.

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

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