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

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

Don't expect to be good at maths or understand things straight away. Be patient and persistent. The most powerful warriors are patience and time.

Tough times never last, but tough people do.

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.

There is no elevator to success, you have to take the stairs.

Success is a journey, not a destination.

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

It is never too late to become what you might have been

Success is the sum of small repeated efforts, day in and day out.

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

I have not failed, I've just found 10,000 ways that won't work.

The journey of a thousand miles begins with one step.

99% of failures come from people who have the habit of making excuses.
