The road to success is like a staircase. If you want to succeed, double your failure rate

I think, therefore I am.

There are no shortcuts to any place worth going.

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. 

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

Hard work - a two way street where you get exactly what you put in.

The greatest enemy to human potential is your comfort zone

I had no time is no excuse. 1 hour is 4% of your day and 1 minute is 0.34 % of your day.

Hard work always pays off - it is not a question of if you will get there, but WHEN you will get there

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

Hope might be a good breakfast, but it makes a very poor dinner

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.

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

Dreams don't work unless you do.

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