Stress

Lots of jewelry designers are self-employed, planning out their own schedule and setting most of their own deadlines. Sounds like a great way to reduce stress, right? Wrong. As great as that sounds on the surface, self-employment is hard. Even the chillest California surfer would get a little stressed out if she were worrying about budgeting, inventory, and steady production for her custom surfboard business.

Beyond the stress of the production side, you'll also be working a lot of weekends and holidays. Weekend craft and trade shows, especially during gift-giving seasons, will be your bread and butter until you've really made it big, so say goodbye to your quiet, relaxing Sundays (source).
