How can a person stop being obsessive? I have a one track mind. I do not multi-task well. If you know me, you have seen it. Working in my yard, quilting, building this block (which was a lot easier than maintaining it), writing my book, writing songs, working puzzles, and probably others I am not thinking of right now. Having an obsessive personality is generally viewed as a bad thing. Like a lot of other things, it is all in how you look at.
I am seventy-five and finally comfortable with my obsessive personality. I accept going into a project or coming back to it that I might not stay interested in it and that I might walk away from it. I am okay with that. In the past, I listened when people reminded me I was good at starting something new but not good at finishing anything. That made me doubt myself and ask myself what was the use of starting or going back to something because I was not going to finish it anyway. It certainly took away from that rush of energy starting a project. I do not think that way anymore.
What works for me is having more than one good obsession so when I am bored or discouraged with one or am obsesssing on one that is not good for me, I can switch off to another one. This does not mean that I walk away from a project everytime I am frustrated or stalled. Sometimes I grit my teeth and refuse to give up. I trust myself to stick with or come back to the ones that matter, even the hard ones. That is where I am with the book. I am not to the walking away point. I accept that I am not making leaps and bounds, so I have to keep my feet on the ground and butt in the chair and put the time in. As long as I do that, I allow myself to obsess with another obsession to free my mind. Tonight it is going to be Doctor Who. Next week it might be quilting.
The answer to the question is you do not stop being obsessive. The secret is you have multiple obsessions.
