WHAT'S YOUR DRIVING FORCE?

WHAT'S MY DRIVING FORCE?
Around the world today, most people seem to be asking themselves this question. Some days ago, i was taking a hike around my neighborhood when i overheard.... i actually eavesdropped on the conversation between two persons and it went like this; Just a piece of it thou.
Mr A: my brother, i really don't know why am still selling clothes when the profit is not much again.
Mr B: hmmm, why did u start in the first place?
Mr A: I thought the business was going to grow after a while....
Critically looking at the conversation, Mr B was asking Mr A what his drive force was.. And at this point, i feel Mr A doesn't know why he started.
One thing i have learnt over the years is that knowing your driving force builds persistence. And, persistence is the only means by which success is attained. I read in a book by Napoleon Hill about a man R.U Darby who had the 'gold fever' and went in search of it. He eventually found gold but what he got was surface gold because he stopped three feet from the main gold ore WOW!! .
Today i would advise you to know your driving force[purpose] for doing that which you are doing because it could build the persistence you may need to keep fighting.
Thank You....
