The best devices and apps to up your selfie game

The first time a stranger on the train told me I had a nice smile, I didn't believe her. Back then, I hadn't yet had my crooked teeth fixed, and my self-esteem wasn't anywhere as high as it is today. I was an ugly kid, and it took a shocking number of selfies to convince myself that I'm not an ugly adult. It may seem like a superficial pastime, but selfie-taking has real benefits. I'm not alone in believing there are psychological advantages here.
