I'm not opposed to the idea of continuous learning and improvement. It's more like in art (and programming as well), I vastly surpassed my original goals, and I'm already overqualified to do anything that I like to do and am interested in doing. I certainly do not have the skill or knowledge to do everything that is possible to do, but I don't care about that.
I suspect my attitude may differ from that of many artists. I'm not on a journey to explore some mystery. I just need the skills to execute on the projects that I imagine.
