Question of the Week: Here are two quotes. Are they mutually exclusive belief systems?

"...99.9% of what goes on in one's life is actually none of one's business, with the .1% under one's control consisting mostly of the option to accept or deny one's inevitable powerlessness over the other 99.9%..."

-- David Foster Wallace

"You can get it if you really want but you must try, try and try..."

--- Jimmy Cliff
