Self Sabotage

Have you ever wondered whose side you were on? I've always assumed I'd at least be for me. So I'm surprised when I find myself the cause of my own undermining. Self sabotage is different than having weaknesses, lacking skills, or making mistakes. It is a deliberate (if unconscious) working against something you, at the same time, are working for. No excuse will suffice. No other perpetrators on whom to lay the blame.
I need to get all of me on the same team here. It's okay if different aspects of me play different roles on the team. I've already come to terms with the fact that I am more complex than I had expected. But it would sure be nice if we (that is, all of me) at least could agree that we wanted to win the game.
