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. 

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.

Procrastination is the thief of time and the enemy of success.

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

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

There are no shortcuts to any place worth going.

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

Just stick with it, what seems hard now will one day be your warm up.

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

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

The greatest enemy to human potential is your comfort zone

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

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

Tomorrow is worth more than yesterday but less than today.

You're not in competition with anyone but yourself. Outdo your past, not other people.
