Looking at your most recent posts, you seem to be struggling. Going back to school will have a lot of work and a lot of concentration. I say this based off my own experience. I tried to go back for a certificate. I wasn’t able to make it through the classes because my focus just wasn’t there. My ambition was but unfortunately that wasn’t enough. Have you thought about trying to volunteer at a local art museum? See how that pans out. Or inquire about auditing a class and see how that goes?
