Wow - Thank you all for your kind words, I honestly wasn't expecting quite that much interest !
Before my first post I decided first that failure is now not an option for me any-more, however I nearly immediately realised that life doesn't quite work that way, and there will be setbacks.
I have settled for a "middle ground" approach and although I had a bit of a wobble earlier today at work, I have resolved that I am going to stick to this.
I will still have wobbles, but I am going to deal with them properly promptly, and learn from them !
