The place in you that resonates with all of Nature, KNOWS.  The more we analyze, the less in touch with that natural essence guiding light and power.  Here's the deal:  Your conscious mind doesn't have evidence that it is safe to trust your gut, mainly because we have not given it much opportunity to do so.  We think and think and think and then act.  And then when we think about it some more, we decide that all that thinking is what made it all work out.  The possibility does exist that it would have worked out anyway.
