This is really sad. I understand you are a product of your times, but it is pathetic to me that you cannot conceive of an interesting life without internet and social media. Do you really think countless generations that preceded you sat around being bored?
As someone who was in his 20s by the time the internet was a thing, I can tell you my young adult life was plenty stimulating despite growing up in a relatively small town.
I was into music and learned how to play guitar, formed a band in high school. We spent many weekends jamming and practicing, trying to learn the songs of our favorite bands. started with classic rock like The Who and AC/DC but got into metal as we improved on our instruments. when we could pull off Metallica's For Whom the Bell Tolls, we really thought we were awesome. our bassist could even do a decent Cliff Burton solo, complete with distorted wah bass
I had my driver's licence at 16, had my first car at 17, we were driving all over the place for concerts. Packed my Toyota and drove two hours for the Clash of Titans tour... Slayer, Megadeth, Anthrax. It was fucking great
