Inner Voice Ousted

One of my obstacles to accomplishing what I want with my life is my doing things that I want to do, but don't really want to accomplish. Indulgences in entertainment and suspension of effort are things I relish and desire to do, but are also things I don't desire to accomplish. I would much rather cease to be sidetracked from accomplishing, but this rarely happens. In fact, it usually out of boredom with the diversion that I eventually turn to that which I need to accomplish. What is it about the meaningful thing that is so repugnant to me?
