That verse seems to pretty much rule out “the pursuit of happiness”.

You picked a rough time to raise teenagers.

Since you put this stuff online I’ll take that as a solicitation of advice. It costs no more than its worth, as it were.

I have no claim to authority, but I will give my version of common sense.

The junior high years are important. I would suggest trying to find ways in which the kids can experience real happiness, the kind that comes only from the exercise of virtue. This can come from music or sports or anything that can provide a sense of achievement. Subtly encourage them to try different things until they find something at which they can be successful. In this way they will learn from actual experience that excessive amusement and materialism are false temptations.

Keep an eye on their grades. If their performance in school drops off that is an indication that there are some unhealthy distractions in play that warrant close scrutiny.
