Noise Cancelling HeadphonesI love these wired noise-cancelling headphones from Bose. I chose wired over wireless because I don't have to charge them, and the cord keeps me from wandering away from my computer. ConvertKitI like things to be easy and straightforward. ConvertKit is an easy-to-use email service provider that lets me do things on my own, without relying on tech help. TeachableI use Teachable to run my online courses. Again, it's easy enough that I can use it without needing tech help.
