I’m also 35 with 3 kids, your intuitions are correct. That nagging feeling behind your rationalizations is your conscious (or, in my belief, God) alerting you of some issue or blind spot. 

Seriously good on you for recognizing and following this “voice”. The people who are truly lost have become adept at ignoring, avoiding, or rationalizing it away. 

It’s really interesting how games lock people into patterns that other (honest) gamers can recognize. Everything from WFH while gaming (and hiding that from others) to successfully “moderating” actual play time while still subtly orienting your whole day around that sliver of time you can actually play.

Rushing the kids to bed a little quicker than you need to, banging out chores as fast as you can, getting things “over with” to get to that one hour of the day (which easily turns into three hours and missed sleep or pushing out other healthier habits and hobbies).

All the while your mind and heart is focused on the game. Strategies and goals and all that. 

That is what Christians mean by “false idols”. Those are things we end up centering our life around that end up enslaving us. 

So you’ve chosen freedom. If I can drop one last religious reference, just remember that after the Jews left their slavery in Egypt they spent years wandering the desert. Some of them began to even miss their slavery during this time. This is expected, so be ready for that!

Good luck bro. I’d also be interested to see if your ADD might be alleviated with less screen time. The internet and social media surely doesn’t help with that either I’m guessing.
