It's not that there's no time for coding in a hobbyist manner, but I'm careful about moderating the amount of time I allocate to it.
That said, I wasn't at even remotely the same level of execution ability as the author, and are probably still not, but I was starting to work with freelance clients in PHP and Angular.js, building some small technical experiments end to end, and relentlessly trying to get better at technical stuff. I could definitely still do that, just not at the expense of other things.
I came to realise I don't even like "real" programming only random quickly put together scripts.
When my friends explored all kind of things I was so stuck on coding and web dev and php. I didn't check out any other fields of interest or professions. When I read all the threads here about parents teaching their 4 year old BASIC to "indoctrinate them into programming", I cringe hard. They're stealing their kids' childhood and their drive to explore what they'd actually love.
Regarding parents, what's made me cringe lately has been the shutting down of opportunities for their kids to form new bonds and play. There's a park I go to regularly that seems to be attended by well-off parents who go in groups. Last time I overheard a kid who must have been 5 playing with some other kid she just met on the swings. She ran over to her mother and said "This is ___ she's my new friend" and the mother basically wrote it off and said that's great but the other one has to go and then they left. The same outgoing kid had earlier wanted to try climbing this artificial rock I was doing, and the parent just showed absolutely no enthusiasm for letting their kid do it, she had somewhere else to be. I get that people are busy, but let your fucking kids play.
