When I think of what my customer looks like a lot comes to mind. One major key is that my customer is an adult, most likely a high-school volleyball coach. Since my product is creating a self-operating volleyball net, I’m sure my customers would be efficient-wanting people, ones that dress nice and have good hygiene. They're hobbies may include volleyball, running, eating healthy, blogging. They either drive a hybrid car (probably green) or a nice black sports vehicle. They most likely watch sports channels or tv sows like Seinfeld. They read lots of self-help books or books about increasing happiness. They are most likely liberal so they support Hillary Clinton or Bernie Sanders. They would probably be in their forties but feel like they're in their early thirties.
One thing I have in common with my customer is that we both enjoy healthy mind and body lifestyles and we both are interested in volleyball. My product was created because I always had trouble setting up volleyball nets for practice and taking them down after.
