We miss extra bits of knowledge that can add value to our lives. We sort of lack empathy because we're multitasking all the time.

We're all not exactly the same person online that we are in real life. I am not as happy as my Instagram makes me look. We are all heightening the positives and downplaying the negatives.

It becomes very difficult for us to adjust to a world without social media because we spend so much time involved with it.

I'm not a fan of the selfie. I think it's at the heart of the narcissism that social media brings into our lives.

One of the things that makes a social-media cleanse so difficult is that every time we log on, every notification we get is an addictive substance. It's just like any drug.

If I post a selfie, and you like it, it's of little cost to you, but it feels great to me. That becomes addictive, and you see people's narcissism so quickly. I think that's a very dangerous thing for us all to be addicted to.

If you can pinpoint the moments in social media that are really negative experiences, those are the ones you can cut out. And when you do, you recognize how much better your life is.
