This particular tweet hits right in the feels.
Surely we've all done this during our youth: when we grow up we're going to do all sorts of things that by being kids we're restricted from doing. But as the tweet points out, once we've become adults we actually end up not doing those things. For example, fried chicken is my favorite food, and when I was little an intention of mine was when I grew up (and have money) I'd walk into a KFC, buy a bucket of chicken, and eat it entirely by myself.
I'm 30 this year and I've yet to do that.
What is it about being an adult that, let's face it, stops the fun? Why don't I play video games all day now that I can now afford all the games and have more time to spare (having to do homework really put a damper on things back then)? Why not eat junk food whenever I feel like? What about staying up late until the wee hours of the morning?
I think as adults our event horizon widens exponentially beyond the present (dull things like saving for retirement): I don't spend a day playing video games because it's a waste of time and unproductive (we can't all be those millionaire Twitch streamers). I pass on the junk food marathon because it'd be much nicer to not have diabetes and heart disease. Burn the midnight oil just for fun? We adults know that sleep is the absolute best thing in the world.
It was indeed true wisdom back when our parents prevent us from executing our fantastical inclinations. In their adult mind they know it to be not good for us. My father never ate a bucket of fried chicken by himself either.
But perhaps it'd be good for us current adults to bring back some of that child-like innocence and narrow focus. Adult life can easily entrap us into always thinking and planning for the future, sacrificing the present (not to say this is bad). Why not periodically think like a child would and say eat ice cream whenever the urge comes to mind? That sliver of joy and escape might do well for our constitution; freshen up our internal batteries for the daily grind.
As an adult, self restriction comes naturally: if 15 year old me made the same money as I do now, it would be completely squandered as soon as the paycheck hits the account (or worse - max out the credit cards). At 30 I'd never entertain the thought. But as with anything, those restrictions can go overboard: it's important to find the balance between living in the now and preparing for a future. A big component to adults getting burned out is when our minds are too frequently into the what-ifs of tomorrow.
So sometimes think like we once did: as a kid. Go overboard! Indulge in those tendencies and wants. Be present.
I'm going to play some videos games for a lot of hours.
