Hi Martin,
Reading your post a couple of things occur to me.
From my memory of reading the Tony Robbins book (and it was a while ago now) there were two parts to his motivational strategy. One was the pain of not changing - the push, if you like, the other was the attraction of spending your time doing something that was truly fulfilling and enjoyable, the pull.
To have a successful motivational strategy it's helpful to have both the push and the pull working together. If all you have is the push it's a bit like turning on the hosepipe but putting your thumb over the end - you feel a build up of pressure inside but nothing actually happens; literally no outcome.

So what?s your pull? What would you really like to make your life about?
Once you've decided that (and for most of us this is the hard part!) then you can start to consider how your current job fits in with this. You then have a choice. You can either feel bad about it, if you really think that this will motivate you, or you can feel good about it because it is giving you the skills / contacts / money that you need to do the things that you really want to do.
Hope this makes some kind of sense.

Take care,
Tim.
