I am quite happy that I don't need to use Instagram or any social media like Facebook in my life. I am a member of Creative Spark and only one other forum (not an art one), where I rarely make any contributions, but check in every day to see the latest communications from other members.
Social media marketing is mostly hype; now and then, an occasional lucky person makes a success of it, mostly via sheer luck, and then he'll tell you endlessly what the "secrets" are. Indeed, some of them even write books or offer courses on it. Almost all of it nonsense. A book absolutely everyone should make time to read is Nassim Taleb's
Fooled by Randomness.
Now social media can be fun; I have been on Facebook just about forever. But the trick is NOT to try desperately to market yourself. One should do precisely what the powers that be at Facebook
don't want you to do, namely to put the "social" back into social media: be FB friends only with people who are actually your friends, and engage with them socially, not commercially. In practice that means you cannot possibly have more than a hundred or so FB friends - no one can keep track of more than that amount of people.
That's how I did it for many years, and I could never understand why people complained so much about FB, until I discovered the complaints were all from people who had thousands upon thousands of FB "friends." Well geez, OF COURSE you're going to see all kinds of horrible and boring and irrelevant and irritating stuff on your timeline that way.
But what about social media marketing and networking? Don't you need lots of online "friends" for that? No. See my point above about social media marketing. It might actually be better to have fifty FB friends who know you and appreciate what you do and therefore regularly share your posts than to have ten million who each ALSO have ten million "friends" and therefore likely never actually see anything you posted on their timeline.
I eventually discovered a little hack one can try on FB: it has a feature by which you can mute a friend, so you remain FB friends but you no longer see any of their posts. I began to accept friend requests from people I don't know, and then simply mute them the moment I see one of their posts. That way they possibly still see mine, but I no longer see theirs, so I can continue online relations with my real friends without having my timeline contaminated by posts from people I neither know nor want to know.
It made little difference anyway; I seldom get friend requests from anyone.
I have found FB moderately useful (once actually sold a painting thanks to FB!), but it's mostly just a fun social media tool. I'm a member of several FB groups (another potentially fun feature) ranging from wildlife to art, where I often see much that is interesting.
But on the whole I would agree that one can (and probably should, really) actually live perfectly well without any social media whatever.
There is a WhatsApp group of residents in my suburb, where we share things like recommendations for good plumbers and other news.
Now THERE is where I draw the line. I once had WhatsApp on my phone. But I am dirt poor and cannot afford cellular contracts and stuff, so I only use prepaid. And found to my consternation that WhatsApp messages burn through my prepaid at an unsustainable rate.
Apart from that, it drove absolutely, utterly, batshit crazy: the phone starts beeping absolutely non-stop, day and night. I could not focus on anything else anymore.
My fondest wish is for a life where I no longer have any phone, whatever, of any kind, apart from
maybe an old-fashioned landline, and in that case, I'd probably take it off the hook most of the time.
