Joe,
Can't a little anger at oneself help in this regard?
Dave
The issues here are subtle. First it depends upon how one perceives anger towards the self. If it is corrective, as you indicate, it can be helpful in generating better (more) attention to detail.
If it is evaluative and this is often based on early experience when anger was used by others to tell us we were "bad" "worthless" people because of our unintentional behavior then it is detrimental.
In general, anger towards self is not good. I would put it up there with cocaine use. Effective but the side effects are far too destructive.
There are other ways to stimulate one's self to perform better and try harder that usually have to do with finding what is good about what you did and being "happy" or satisfied with your efforts.
We all respond better and more effectively to praise than to fault finding. When others (or our self) finds fault our first reaction is usually to defend ourselves.
If we respect the person who is angry we tend to cringe or be sorry that we hurt them and caused them pain. Neither of these reactions make us better players. They may make us put forth more effort but the effort is directed towards pleasing someone else. The effort should be to please our conscious self because this is what leads to long term progress.
Don't get me wrong here I am not a touchy feely kinda guy. I seriously think that your dog is more intelligent than the average two year old child. Children learn through fear and strong guidance which is later reorganized as respect.
In psychology the usual statement is that
punishment stops ongoing behavior, it does not teach anything. So if anger is punishment it is not useful. If anger is used to make one pay attention it may be useful -- but there are better ways.
Oh and feisty women make my life better. Hell I was married to a redhead for 27 years and her daughters are not much different.
PS. an addendum to hu's comment is that the conscious is often seen as the mediator between the subconscious, the unconscious and other parts of the psyche. Which is in service to the other is more like three brothers trying to get along. Some times one is dominent somtimes the other. The analogy breaks down if we think of these processes as individual entitites, they are not. They are all processes that overlap and interact within the same person.
