There is some mind-boggling research down by Seth Godin about the "reptilian brain". That refers to the limbic portion of the brain that is basically used for survival.
I have been battling with it constantly. I wake up and proceed to nag myself to do things that I am going to do anyway- like brush my teeth etc. I get down on myself for getting down on myself and have been at a loss as how to control it.
But his research has truly "reframed" my thinking.
Instead of getting down on myself for nagging myself I have been thanking my reptilian brain. "Thanks for the reminder!" It is doing its' job and has been doing it quite well. It is actually comforting (and I never thought I'd get there).
The same can be extended insofar as perfectionism is concerned. I also tend to be super-organized or not.
Yet no one does everything or anything (for that matter) perfectly so just do the best you can and let it go. Easier said than done I know!
I have hoarding tendencies and have had them since I was a little kid. A lot of it is related to PTSD which I confirmed with a psychologist from "Hoarders".
One can take photos of stuff you really do not want to part with but no longer need. I also think in terms of how much space an item is going to take up. I learned that from travelling. No one received sombreros from México from me- silver or turquoise or black coral is pretty and is light.
I save political (etc) buttons and I can have a entire collection and so what? I have that much room easily. Books are a real problem but I love them with a passion so I am just trying to keep the ones I really want.
Now many books are public domain so I do not need all the classics. I can find them free on Gutenberg. Almost all info can be obtained online. And anything else you can find on Ebay and/or Amazon!
Seth's research really is focused on creativity. I need to delve into it. I am a great one for the unattainable. If I cannot do it perfectly... well... I get sidetracked. I love arts and crafts and have so much "stuff" but I found a neat rolling cart and everything is at least under control. I am not ready to part with the cool stuff and that is okay. I forgive myself. (Or I am trying.)
I'll move on to what I can get done.
Same goes for writing. I love to write with a passion. I have routinely been writing 20 page letters since I was a kid. I excel at it. All that practice sure helped. But I want to write perfectly. I also get too many ideas (same thing with crafts). Just like insofar as this comment is concerned. HA!
Also a few years ago, most of my stuff was stored with relatives. I had very little stuff. It was not the answer to all my problems.
But the most effective therapy is watching an episode of "Hoarders'! LOL.
"Yumm, tamales!"
