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

He who has begun his task is half-way done. Have the courage to begin!

If you want to succeed, double your failure rate.

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. 

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

Success can never happen without the journey (struggle).

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

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

It is never too late to turn an unproductive day into a productive one.

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

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

The journey of a thousand miles begins with one step. 

If you fail, next time fail better.
