I know...it's something that I'd really like to work on eliminating from my life but am not sure what concrete steps to take as this is somethive I've probably done for about 30 years now. When I find myself drifting into imagining the (negative) future, I try to distract myelf and find that yoga also helps to focus the mind by focusing on breathing. But, I definitely go to it in weaker moments and am hoping others may have some additional mental "tricks" that I can use....I'm not a backward looking person (don't really like talking or focusing on the past) but I have a LOT of trouble staying in the present....my professional life is centered around anticipating future problems and this doesn't really help in my personal life. Basically, ferretting out the bad stuff for clients is what I'm paid to do, so I'm always trying to anticipate the negative so that the clients can fix stuff before everything really goes down hill. I'd like to be able to use my skills in the area for work but then turn it off when I leave the office...not been too successful so far though!
