Your fear of having a mediocre life should be much greater than your fear of rejection.  What is your fear in starting your own home based business?  Is it fear of the unknown?  Is it fear of what those around you will think?  Is it fear of being alone and not part of the cubicle crew?  Is it fear of failure?  Did you know that the two greatest motivators are fear and greed and that 99 out of 100 people let fear rule their lives...  The first step toward success is simply to start.
