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

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

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

You cannot escape the responsibility of tomorrow by evading it today

Work ethic is important, because, unlike intelligence, athleticism, or charisma, or any natural attribute, it’s a choice.

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

Success can never happen without the journey (struggle).

A book a day keeps the stupidity away.
