ALLLLLL the time.

Only when I'm trying to sleep????

My hobby and trade (rock climbing and construction) demand immediate action without thought in some situations. So part of my head will function that way, even in less pressing matters.
But gimme a good bong hit and a sunny field and I can contemplate one blade of grass for three weeks, blissfully.

I wouldn't say "overthink" but maybe think a lot. I read a lot of periodicals and non-fiction. I am involved with numerous groups that are active in environmental/historical areas. This site has especially gotten me going. Don't look at my dining room table. It has become a desk with all kinds of scrap paper covered with notes.

I have been called an ANALyst Nuff said. LOL!

Hmmmmm.....

Hmmmmm.....

Hmmmmm.....

Maybe. .

I really think things through, I am a half decent strategist so it is necessary.

I think I managed to arrive at the point of understanding that one needs to know when to say 'enough' in all things in my mid twenties. It is too easy to get caught up in that closed loop that keeps one from making decisions, finishing a project, or terminating a poorly chosen battle or relationship.

Here's an example: Every writer I have ever known has a hard time not doing 'just one more rewrite'. It is common for us to just keep on keepin' on with something that could have been published 6 months ago. One really needs to know when they're watering a dead tree. This is true in all endeavors. I can tell you that I have never sent out a manuscript that within a day or two after having done so I didn't kick myself for not doing one more rewrite. It never fails.

Ugh. Yes. I've 99 problems and 96 of them are completely made up scenarios invented by my brain!

Yes. By the time I am awake and out of bed in the morning I am pretty well convinced that when I look out the window I will be seeing mushroom clouds on the horizon in every direction.

Tendency? My whole life is devoted to overthinking. And then I under think to compensate. Not good.

Yep and I'm extremely detailed. I need to know... every... single... little... thing. I'm sure I've driven some guys a little nuts with that.

i need to go think about it.

Most definitely so for me and it is almost paralyzing sometimes not being able to come to a conclusion.

I'm overthinking this question right now.

Oh hell yes.

If I don't like something I tend to pick it apart, if I like it I'm more easy going.

I do it all the time - and act on hidden subtexts that aren't really there as a result.

Oh yeah, been there, done that.
