Third strike at writing attempts

Once again my writings just haven't worked. Decent ideas -- if there's an SF paragraph writing contest, let me know... but nothing will develop properly even into a short story. Once again I wonder, does that mean it was the right thing to take a B.Sc. instead of a B.A. or would I have become a writer if I'd been an english major? Now I suppose I'll never know but I believe I chose the right track.
