There are times when an opportunity will present itself.  Some of those opportunities are good; some are bad.  How do we distinguish between the two?  We cannot always do so.  Job opportunities, for example, can be shrouded in mystery, intrigue, and fear.  Sure, a job here might pay more, but am I going to be happier?  Is the drive worth the job?  The grass is not always greener.  It can be, but it can be a disaster.  Sometimes, we just have to take the chance.  Sometimes we need to rely on instinct.  For all of you Star Trek nerds out there, Ferengi Rule of Acquisition 9: Opportunity plus instinct equals profit.  (No, I do not know the Rules of Acquisition, but I knew there had to be one about opportunity and profit somewhere in there.)
