Amazon makes it fairly easy to list and sell old books on its marketplace. You can make more than just a few bucks If you have pricey text books from college. Be sure the books are in good condition. You'll get negative reviews if you attempt to sell books that are falling apart. Remember, add value where you can, no matter how small it might be and no matter how few people might readily notice it.
To avoid any confusion, I want to make it clear first that virtual assistant work is not always non-phone, but it can be. Virtual assistants tend to do a little bit of everything, just depending on their skills/expertise. So if you are good at various non-phone tasks (social media marketing/moderation, writing, graphic design, research etc.), then you may be able to do work for some of the companies below putting those non-phone skills to work.
