Overview
Do not be afraid of embracing all of your opportunistic tendencies -- sometimes, they are your best defense against falling into a lousy routine or succumbing to a rather boring life. Picking up the ball when someone else drops it is not a sign of disrespect to that person: It's a wise way to make the best out of a negative situation. You shouldn't limit your own ambitions with a misplaced urge not to hurt anyone else's feelings. Looking out for 'number one' is not a crime.
