This is a great post (see below). I would add a number of other things.
But the one that really stands out for me is Passion.
Passion to want to achieve something.
Passion to be better at something!
Passion that pushes someone through difficult times.
You know that kind of energy that inspires others to want to get up off their backsides and DO something worthwhile.
Too see what is possible and go for it!
