I have been good at hanging on art life wise.
I have had doubts all of my art life. I am old enough to say this.
I am glad that, I've made it this far. I haven't worked to the point of overwork, just steadily. I think being diligent is better than working too hard.
I try to pace my self through tasks. So far it's worked. I figure my art life is a marathon and not a sprint. I get to hang in and hang on.
