It's funny: I spend time in the book criticizing social media, but I'm also aware that a lot of my success is because of social media. I can broadcast myself and my work to thousands of people that are following me or my friends. I do think that social media can be good for self-promotion.

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.

Social media has a way of changing your mood. I can see a picture of my ex, and it ruins my day.

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.

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.

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.
