I found that it's less about social media, but about not being able to consume more complex content, because you are burnt out at the end of the day, or even the weekend, and therefore falling back to cheap "intellectual calories".

That doesn't go away just because you cut out one potential source of cheap calories. It gets better by first cutting out the source of drainage, which can be very personal. Too many disruptions and pointless interactions in your workday, long commutes, etc.

So I would first try to eliminate some of those, don't fry your brain completely towards the end of the day, and then read. It's much easier with a fresher brain.

It's also possible to read early in the morning, when you're not drained (assuming you still get enough sleep).
