I've read most of your posts. I tell you any step in GAL is good. My sit has been sliding over the past 10 months - but I do feel good. I long for my W, I can't understand her, etc, etc, I'm not detached - maybe a little. But, my GAL is awesome.
Make any small change and you will get momentum. If you go to starbucks carry a thermos of coffee, if you wear jeans, switch to dress pants, change the way you get to work, etc,
I started decluttering the house and it made me feel great. It did not cost me anything, no major time commitment, etc. I did a couple of items a day. It gave me a real sense of accomplishment.
The biggest mistake I made was keeping my marital problems to myself. Get support - call your friends, see your clergy, etc, etc. It really helps.
The GAL will come - just start with anything.
