Wht drives ppl?!?!

I wonder.. wht is it tht actually drives ppl. Wht makes them do whtever they do.... the decisions they take.... the choices tht they make....

i feel - Sometimes its their will, experiences of life which have led them into a path... sometimes indifference towards an aspect or its whole or just probably the phase of life they are in...

Sometimes it is a consequence of decisions already taken, theirs or somebodyelses'. And yes ofcourse the balance with an intrest and a yearn for wht they love..

Whtever it is tht is drivin them right now to do it is much more important than the act itself. It decides the quality, defines their attitudes and makes the small little changesin their lives and in ours...
