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.

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

"I" not them. Be the best version of you.

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

Pure mathematics is in its way, the poetry of logical ideas.

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

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

Failure is NOT your destiny. Failure is the key to success.

Work like you don't need the money, dance like nobody's watching and love like you've never been hurt. 

Success is not final, failure is not fatal.  It is the courage to continue that counts.

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

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

You cannot start the next chapter of your life if you keep re-reading the last one.

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.
