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

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

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.

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.

I think, therefore I am.

The journey of a thousand miles begins with one step. 

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