There’s this book called “Deep Work” that some people (me included) like. From the things I’ve taken from it one is “embrace boredom”. Basically, being bored these days is a skill that takes development. And it really does wonders to having a clear mind, coming up with original ideas, etc. The biggest challenge when doing this is that I’m so accustomed to using the internet as part of my thought process that it’s really difficult to not use it to verify some idea.
I agree with that philosophy, not trying to cram every free moment with content. For me embracing an athletic lifestyle has been a great way. While its not embracing boredom, its at least fun, fulfilling, and positive. Also language learning has been a great interest to pursue
But yeah, try learning to be bored.
