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

Success is a journey, not a destination.

Time is your friend, impulse is your enemy.

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

I think, therefore I am.

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

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

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

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

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

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

You cannot escape the responsibility of tomorrow by evading it today

A hero is no braver than an ordinary man, but he is braver five minutes longer.

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

Success can never happen without the journey (struggle).
