If you approach stuff with positivity, openness and wonder you'll have a blast! This is my current experience with learning Go, having learned Python previously.
I don my explorer's hat and force myself to live into the text, subject or code (Herder's Einfühlung). Personally it makes the journey so much more entertaining than merely as a tools to an end.
It's joyful to obsess over stuff; to try and get better; to try and understand.
There's two things, IMO, that get in the way as an adult:
* The crush of ordinary responsibility can not leave enough time for exploration and wonder.
* Related: We just get used to following a routine and not completely losing ourselves in something new. Maybe we tell ourselves we can't get good at new things anymore like we used to.
Revisiting old stuff, like Monkey Island, is fun; but it's not nearly as intense as something new. I'm looking forward to it and it will be entertaining to share with my family. It's been awhile since I've found this kind of pure fun and intensity in video games, but I'm sure it'll happen again.
