IN!
Thank you for a most interesting OP MidnightBlue, as someone alluded to earlier (Dee I think) a lot of the time we get stuck because we fear change and we fear trying to change and failing. I knew that if I stopped drinking for even a short time I would yearn for a drink until I would eventually buy some. The thought of feeling like that permanently stopped me from making a serious effort to quit. It was only when my life became so unbearable through drinking that I finally faced up to what I was doing to myself. I was 54 and wish I had done it decades before but I left until I had no other choice.
On a different form of getting stuck, some years ago I got literally stuck in World War 2 tank, they cut the entrance hole too small you know. I ruined a good pair of jeans not to mention the humiliation of it all. If anyone wants to buy me one I am an XXL in tanks.
