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

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

Time is your friend, impulse is your enemy.

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 master has failed more times than the beginner has even tried

Skills are built not born.

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.

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

Everything you want is on the other side of fear

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

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

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

Tough times never last, but tough people do.

I think, therefore I am.

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