3. Start a Retail Business
Many retirees opt to open their own retail business. If you have a large collection of any kind, an attic full of dusty antiques, or boxes of books you no longer read, you may have the initial inventory needed for your own retail business.
The Internet makes it easy to start a new online business because of the relatively low overhead costs of selling and advertising online through sites like eBay and Craigslist. Additionally, you can sell items in a rented space at a brick-and-mortar store, or rent a booth at a flea market.
If you plan to start your own business, look to your local chamber of commerce and the Small Business Administration for resources. You can also start a website to advertise your services, and utilize social media to promote your business.
