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. 

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

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

Tough times never last, but tough people do.

The master has failed more times than the beginner has even tried

Never underestimate the importance of small steps. small steps = big changes. 

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

The greatest enemy to human potential is your comfort zone

The journey of a thousand miles begins with one step. 

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

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

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

If you really want something you’ll find a way. If you don’t you’ll find an excuse.

Success is the sum of small repeated efforts, day in and day out.

Hard work beats talent when talent doesn't work hard.
