I think I know what you mean! Some of my biggest changes happened so gradually I didn't notice right away.

I personally feel like I'm at the point where I'm trying to change the toughest things for me to budge. Therapy to me, in a way, is like that old saying about boiling frogs slowly--if you turn up the heat gradually enough the frogs don't jump out!!

(thankfully, therapy has better results than dead frogs)
