I like breathing and relaxation exercises, I usually do these when I want to be left alone or when I'm on the train commuting which is pretty much all the worst elements of modern life packed into a sardine can. I can get so relaxed that I'll miss my station. I don't see them as a way of making changes, more as a way of coping.

I don't know why I've never pursued meditation further, maybe it is the "stiff upper lip" Brit in me that holds me back.
