Doing something new or different is never easy.
Occassionally though what you are currently doing hurts real bad. The knotted tummy feeling that will not go away, the restless energy screeming to you 'something's wrong, get out get out get out.', sleepless nights, the feeling of waste... oh you put up with all this for a while, well as much as you can, and then you think 'I just have to make a chnge.' And you do, and yes the pain doesnt go instantly away but a month or so later you think 'why the hell didn't I do this sooner?'
