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

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

I can is 100 times more important than IQ.

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.

Dreams don't work unless you do.

Each day is an opportunity to improve. Aim to be that little bit better than yesterday and better tomorrow than today.

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

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

Time is your friend, impulse is your enemy.

It doesn’t matter where you start, it matters how you end

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

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

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

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