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. 

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

The greatest enemy to human potential is your comfort zone

Instead of finding reasons why you can't, find reasons why you can.

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

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

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

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

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

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

I think, therefore I am.

Success is a journey, not a destination.

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

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.
