It was a tough decision for me, too, J. But, the reality was greater than I wanted to believe, I simply could no longer keep that pace. When I left my regular job, I was in a huge attack that lasted a very long time and I had begun to think it might not end. It did end and I was faced with what to do next. I freelanced for about 5 years after that and did pretty well with it, until the disease acted up again.
It was frightening and hard on the ego, but I stopped taking clients and got serious about fulfilling my dreams and goals. I do not regret that choice one bit, I'm very glad that I seized those opportunities when I did because most of it would be impossible for me now.
It looks to me like your next season in life is on the horizon and it will come in due course.
