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.

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

You cannot escape the responsibility of tomorrow by evading it today

Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

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

Do what you have always done and you will always be what you have always been

Your attitude is everything. Pick a good one.

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

The greatest mistake we make is living in constant fear that we will make one.

Life is full of opportunities. With every opportunity that is missed, another one is born.

Everything that happens was once a dream.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Practice like you’ve never won. Perform like you’ve never lost.
