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. 

Time is your friend, impulse is your enemy.

Twenty years from now you will be more disappointed by the things you didn’t do than the things you did do

Don’t practice until you get it right, practice until you can’t get it wrong.

Whenever you find yourself doubting how far you can go, just remember how far you have come.

He who has begun his task is half-way done. Have the courage to begin!

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

The journey of a thousand miles begins with one step. 

It is never too late to turn an unproductive day into a productive one.

We all make mistakes. What matters is how we choose to move forwards from them.

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

The boxer is not afraid of being knocked down, he is afraid of not being able to get up again.

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

Be strong enough to stand alone, smart enough to know when you need help, and brave enough to ask for it.

Don't fear failure, fear being in the same exact same place next year as you are now.
