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

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.

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.

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.

Each person can achieve balance by cutting a few things out and seeing how it goes. If you cut something out, and it goes well, and your life is better, you keep doing it.

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

We get one of these little pings on our smartphones, and we get a little hit of dopamine as well. We get excited. We feel anticipation. As we feel this, we want it more and more. So we spend more and more time looking at our phones.
