No one should believe in your own abilities and potential than yourself.  We all have self-doubt; we all have that little voice in our head that tells us that we can’t do something or we are not capable enough, and this in turn limits what we believe we can do.  But our close circle of family and friends usually have more belief in our abilities.  If you are not your own biggest fan, you need to start right now!   Walk that fine line of ‘confidence’ and ‘narcissism’ (its a tightrope!).
