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

Whenever you find yourself doubting how far you can go, just remember how far you have come.

Everything that happens was once a dream.

The greatest mistake we make is living in constant fear that we will make one.

Success is not final and failure is not fatal. It is the courage to continue that counts.

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

Hard work beats talent when talent doesn't work hard.

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

He who has begun his task is half-way done. Have the courage to begin!

We all have two lives. The second begins when we realise we only have one. 

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

Lose an hour in the morning and you will spend all day looking for it.

The wise person knows that no answer is also an answer

There is great wisdom in being able to realise that you don’t understand something before it goes too far.

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