Do you have any suggestions on how to help people achieve and maintain good mental health?

It's true that addiction is ultimately a psychological problem. It's true that people engage in addictive behaviors as a coping mechanism to avoid difficult emotions.

It's also true that the Internet has enabled a lot of deliberately addictive content. Phones keep that content constantly at hand. And it's difficult to avoid having a phone since they also provide utilities.

I'd like to live in a world where everyone had such great mental wellness that they were impervious to the temptations of their phones. What are some serious tactics to make that happen?
