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. 

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

Shoot for the moon and even if you miss you’ll land among the stars/

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

Everything you want is on the other side of fear

Everything that happens was once a dream.

Success is a journey, not a destination.

The greatest enemy to human potential is your comfort zone

No one starts out on top. You have to work your way up.

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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

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

You can have results or excuses, not both

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.

Start, struggle, fail, fix and learn. Repeat.
