Tbh there are people who are never bored, because they have a strong intrinsic motivation to try new things or improve. Usually in things that arent jobs, like hobbies or volunteer work/clubs.
For example I would love to improve my programming, switch to linux, set up home server, learn how to lockpick, go climbing or pick up bodybuilding and build cardio, redecorate my home, maybe dive into streaming game-speedruns…
There are always more things. Once learning how to setup a server, there come more servers to learn about. After learning to program in one language, there come other languages and interesting programming projects etc. And along the way, you’ll hear about and discover other interesting hobbies to check out. Maybe learning how to lockpick and learning how to program combine to learning about hacking, or cyber security. It goes in and on. There are always more interesting things to learn if you’re curious.
I also am an endlessly curious person haha!
Well maybe you never get bored, but I certainly do. And I’m far from alone there. Sure, there are always more interesting things to learn if you’re curious. There’s also only so much energy you can put into them. And if you devote a lot of your energy to one of them, it’s basically an unpaid job. Which is fine if that’s what makes you happy, but it’s still a job.
