Good mathematics is not about how many answers you know... It is about how you behave when you don't know.

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

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

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.

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

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

Practice makes comfort. Expand your experiences regularly so every stretch won't feel like your first.

Success is a journey, not a destination.

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

The greatest glory in loving lies not in never falling, but in rising every time we fall.

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

Tough times never last, but tough people do.

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

The journey of a thousand miles begins with one step. 

Dreams don't work unless you do.
