If there is something in your life that you are rationalizing or justifying, it is something you should think about changing.
yes, think about it maybe.
But I find rationalising is something I do when I feel I can't change something right now, to make it more acceptable to me.
I can tell you what is something I have discovered about change recently- the things which jump out at me and make me angry or want to close the book etc. I am starting to look at those reactions and work them out.
But I think that's because I can, I've moved on with other stuff and it's freed me up to look at that. If my life was still in a big mess I would probably just shut the book *snap* and let it go for now...
