Is goldsmithing a viable profession to take up nowadays? Or even a lapidary? I've been curious about working within those types of artistic handicraft ventures but i didn't have much luck in finding any substantial information of what it's really like to do that for a living and the up/downsides to doing business in those fields. I just want to get decent at any type artistic craftsmanship and work for my own account while still having time to follow other artistic ventures as well (such as writing), but nobody has ever been able to tell me if it's doable or if it's too far up in dreamland to be achievable.
I don't even know how or where people learn how to do that stuff.
