You can be shown the path, but only you can make the first step.

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

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

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

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

Failure to prepare = preparing to fail

I think, therefore I am.

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

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

The bad news is time flies, the good new is that you're the pilot.

Success is a journey, not a destination.

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

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

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

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.
