Neil,
There is nothing I can add to the advice given already in this thread, from some very wise men.
I know you will do well in whatever you pursue, you have already shown those of us who have been here a while what you can do.
I think I can speak for all of us, that we are here for you, if ever you should need advice or just a small push to get you going, should you stall in your pursuits from this point on.
Proud to call you a friend, that is certain. You are an inspiration to some of us, at times.
Keep it up, you will do great things in your time. Your determination is an awesome trait to have.
