Starting Another Business - Day One

My plan was to start a new business when the kids went back to school. I'm chronicling this new business on my blog as a bit of accountability for myself. As a little bit of backstory, I've had a couple of online shops for a number of years. The oldest one is focused on Washington DC themed apparel and gift items but over the years I've added a lot of other topics. My other shop is similar to the first but it's on a different company's platform. This year I opens two new, niche stores online. For My Home is a home decor shop while Ready to Wed sells wedding stationery and bridal party gifts. Ok, enough backstory. Getting back to my new endeavor. My plan was to start a resell business the week my kids went back to school. I am having trouble deciding what to sell. My advisers have wanted me to go into selling furniture. This is a good idea, however, there are some barriers. I am a small person who drives a small car. Until I figure out how to overcome those obstacles, I wanted to deal with something smaller like books and dvds. Yesterday I set out buy books to resell. Immediately I ran into another obstacle. My app to scan books for value prior to purchase wasn't working properly. I scanned several books but each time the app gave me an error message instead of a value. I've used the app before so I don't know what went wrong yesterday. Day 1 Purchases $0 Sells $0 Lesson learned: Have a back-up plan.
