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

Success is a journey, not a destination.

I can is 100 times more important than IQ.

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

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

Everything you want is on the other side of fear

It doesn’t matter where you start, it matters how you end

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

The journey of a thousand miles begins with one step.

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

Run in the morning before your body figures out what you're doing

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

You cannot escape the responsibility of tomorrow by evading it today

Work on your weaknesses until they are your strengths and work on your strengths until they are second nature.

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