Everything you want is on the other side of fear

The temptation to quit will be the greatest when you are about to succeed

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. 

The greatest mistake we make is living in constant fear that we will make one.

Skills are built not born.

You cannot escape the responsibility of tomorrow by evading it today

Your attitude is everything. Pick a good one.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

I can is 100 times more important than IQ.

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

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

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

Procrastination makes easy things hard and hard things harder.

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

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