This sounded pretty weird at first but I've been thinking, and it's probably worth a shot. Are you relatively stable? If you're unfocused or a bit topsy turvy maybe randomness isn't your best bet - but if it's constant enough, the feeling you've described, then there's an idea called "bubble hopping" you might be interested in, that fits well with the Reader's Digest article this topic refers to: in a nutshell, everybody lives inside their own unique reality bubble, and bubble hopping is the process of jumping into unique realities - hopping from one bubble to another - that are removed from your own, at each and every opportunity; a bit like Jim Carrey's Yes Man, only you're more proactive in seeking unique gatherings to go to. So on Monday you might find yourself in a political forum for a party you'd never consider voting for, Tuesday playing Bingo, Wednesday at a gathering of vintage wine enthusiasts; so on and so forth.
We're only really products of the things we meaningfully experience, so when you think about it, a lot of the depressive 'hardening' people seem to go through as they get older, is probably less to do with their neurology hardening, and more to do with their being in a constant close-knit feedback loop of their own making, that works to reinforce their identity according to their chosen surroundings, over and over and over again - and I think the mind at a metacognative level becomes gradually compounded by this, leading some to mid-life crisis, or depression, or even a quiet inward desperation.
By shaking things up and forgetting about comfort zones and putting yourself in unique and exotic social environments, that all flips. You will not only be flooded with a wealth of new concepts and connections to contemplate - and dream about - you will be satisfying the deep urge to learn that exists inside all of us. Not to mention, how much more confident and socially able you're likely to become by challenging yourself in such a regular and achievable way. Makes sense, don't you think?
