"Just do it, you've got nothing to lose." In my experience, the people that make this statement rarely understand opportunity cost. It took me years to figure out that it's OK to let new opportunities pass you by if pursuing them would take your time away from the opportunities you're already committed to. The more successful you get, the more opportunities come your way, so I think this is something successful people have to figure out eventually. If you make a success of one opportunity, it's always at the expense of another. It's good to be selective.
