I was a psychic reader form 1990 to 2005. I was good (still am - with a different focus) made a lot of money, was locally famous, had groupies - insane part.
I stopped because too many people were becoming dependent on my predictions, but more importantly I began to do healing work. I offered people ways to heal the blocks that stood in the way of what they wanted to create. In other words I handed the power to them so being psychic wasn't needed anymore.
As a healer/seer I'm semi-retired - just turned 70 and I never worry about having enough work as a healing conduit.
