Do everyone still complete games 100 percent?

Playing rpg games always have these easter eggs, secret missions, map completion where you have to navigate to every corner of the map. These things may tell a backstory of a character and would make the story complete.

I used to love doing these back then where not everything has been discovered. I just got back to playing a open world rpg and sometimes it feels tiresome to do quests anymore, some stories now are not as interesting as it was before. I developed some kind of ocd where i need to finish all the sidequest first before continuing with the main quest. And now it doesnt hit me as it did back then or maybe i just experienced also doing tasks for real people in the corporate world and think its really tiring. Also on games with multiple endings i used to replay games and play out different scenarios but now i just played one route and watched all the probable endings on Youtube.

Maybe im just getting old and my perception of things isnt the same anymore. No more late night gaming for me and i need atleast 6 hrs of sleep or it would greatly affect my day. Cant binge games anymore. Anyone here feeling the same? Am i being sinked to the real world. Am i just becoming a cog.
