Well, my parents were the first impediment I would have to say. Then my mother's religion. I think how you rise above it, depends a lot on your basic personality and if there is intervention from others that come into your life. Or circumstances.
Unfortunately, my personality is pretty docile and trusting. I've been in a box most of my life and still struggle against being influenced. No support from parents in art and the religion X'd it out. I only did art in a commercial sense when i left for a short period. Too bad the fear of Armageddon drug me back in.
So many ingrained pathways at this point, that progress is slow. Oh Well.
