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

Hope might be a good breakfast, but it makes a very poor dinner

Everything you want is on the other side of fear

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're not in competition with anyone but yourself. Outdo your past, not other people.

The easiest person to deceive is yourself.

Time is your friend, impulse is your enemy.

There is no talent here. There is hard work and obsession. You could be anyone if you put in the time.

We learn more from failure than we do from success.

You can hire a tutor but you can't hire someone to practice for you.

The journey of a thousand miles begins with one step. 

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

There is no elevator to success, you have to take the stairs.

You can have results or excuses, not both

99% of genius comes from hard work, the remaining 1% comes from innate talent
