Failure to prepare = preparing to fail

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. 

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

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Don't put off until tomorrow what you can do today. If today you have no time, it means tomorrow you'll be too tired and the next day you'll be something else.

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

Failure is not the opposite of success, it is part of the success.

Your attitude is everything. Pick a good one.

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

It is never too late to become what you might have been

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

I have not failed, I've just found 10,000 ways that won't work.

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

You cannot escape the responsibility of tomorrow by evading it today
