Success comes with risk and risk invites failure.  Keeping failure at bay can become quite an undertaking for the likes of those previously described. In fact, everyone at some time or another has experienced hesitation around diving into the deep end of the swimming pool, even knowing they could swim. It's cold at first, but invigorating.  Eventually you begin to adjust providing you don’t hop in and out of the experience. Success does not come with keeping one foot in the shallow end and one foot on the pool deck either.  It comes with a full commitment to the experience.  This is where we get the old adage... Sink or Swim. 

Creating methods or an understanding for minimizing risk is always desirable and we have found that coming to understand one's self is the first order of business. Getting to know you, will open the door to being able to better relate to opportunity and those around you thus insuring greater success. Check out many of the self discovery programs available and seek a professional when making decisions around subjects that you are not well versed in or do not have a natural understanding of.
