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. 

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

Don't fear failure, fear being in the same exact same place next year as you are now.

Don’t be afraid to work hard and find out how good you can really be.

Don't be afraid to take an unfamiliar path.  Sometimes they're the ones that lead you to the best places.

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

Success can never happen without the journey (struggle).

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.

Do Not Be Afraid To Make Mistakes. Each mistake teaches us something.

Tough times never last, but tough people do.

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

Everything that happens was once a dream.

Fall down seven times, stand up eight.

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

Lose an hour in the morning and you will spend all day looking for it.
