Rumination

Stop thoughts have always helped me. An example of a stop thought I use is to just yell "STOP!" to myself. And then I shake it off physically, take a shower, or stand up and walk outside just to breathe the fresh air.

Personally I find rumination very, very difficult and tricky . For me to at least a certain extent there is normally a particular subject or issue that requires my attention legitimately perhaps to the point of generating a pro and con list to work out the matter . It often leads to over analyzing and rumination when I often take things too far for too long . I have to make myself stop and tear myself away from the issue and make myself move onto something else or otherwise I will end up in the counter productive category which often I end up in.

Someone said this the other day and I thought it was amazing because it actually worked. It was "if you can't solve this in 5 minutes move on." I have a lot of work to do so I ruminate for 5 minutes and then I just got back to work, still kind of ruminating, but it went away because I became so focused on my work. When the thoughts would come back up I'd say to myself "you couldn't solve this in 5 minutes so just wait a little longer until you're done with work to figure it out." You could even delay things by thinking "I'll think about this in 5 minutes, but right now let me do x or y" and I tend to really get lost in time so that also worked for me.
