No phone for 3 years now. I am so much happier. Every excuse you have in your brain right now is moot because we survived the 90s, and with probably higher attention spans.
I have several excuses: one, yes this worked in the 90s, but as smartphones shape the culture now, they are a soft, sometimes hard requirement, now that they are widespread. We did fine without the internet and credit cards too, but not culture, business, life relies on it.
Second, surviving is a very low bar. Maybe it's not such an excuse to set it a bit higher. Living organisms survive all kinds of ailments, abuse, deficits and other bad situations. Yet, it's not "fine" to inflict these on each other at all.
Third, what works for one, doesn't necessarily work for another. It's great to find something that's working, but humans are different, their situations are different, they are at different stages of life, and so, advice in general is not very universally applicable.
