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. 

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

Everything that happens was once a dream.

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

Success can never happen without the journey (struggle).

Our fixed mindset builds our cage, fear keeps us in it.

99% of genius comes from hard work, the remaining 1% comes from innate talent

If you can understand just one thing thoroughly, then you will understand everything.

Practice like you’ve never won. Perform like you’ve never lost.

Skills are built not born.

I can is 100 times more important than IQ.

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

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

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

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