What's a reasonably lucrative craft?

By craft, I mean something I can specialize in making with my hands, and spend the next few years learning and apprenticing. Something that could be reasonably lucrative if I’m successful. I spent my childhood working with lathes, table saw, drill press, and other woodworking tools. I loved it, and now I’m thinking I’d love to find some kind of craft to specialize in, for example violin-making. It doesn’t have to be wood. Now, I realize learning to build violins is a lifelong pursuit and only a select few can make a living at it, but I’m willing to think boldly. I’m looking for suggestions. Anyone have ideas? Instruments? Instrument stands? Lamps? Chairs? Talismans? Cutting boards? Jewelry? Knives? Picture frames? Spice grinders?
