I was just reading
an interesting article today about scriptwriters. The article talks about fear. If we get drunk and fail, we can blame it one the being drunk. If we are sober and fail, we have to look at our own limitations (talent, discipline, etc.).
I am an expert at self-sabotage and I think this may have something to do with it. However, that does not change that the fundamental step to solving the problem, which is putting down the drink.
