A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

Everything you want is on the other side of fear

Procrastination makes easy things hard and hard things harder.

Knowledge is of no value unless you put it into practice.

Success is a journey, not a destination.

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

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

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

Don’t be afraid to work hard and find out how good you can really be.

I fear not the man who has practiced 10,000 kicks once, but I fear the man who has practiced one kick 10,000 times.

A book a day keeps the stupidity away.

Success can never happen without the journey (struggle).

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. 

You can be shown the path, but only you can make the first step.
