Boredom isn't necessarily a bad thing. For me at least, whenever I'm bored I use that boredom to inspire some creativity and imagination. Honestly, I feel nowadays we're not bored enough since we have endless access to stimulation. And then when we are bored we don't know what to do with it. I'm definitely still working on utilizing my bored time better, still prone to filling that time up with meaningless consumption of social media or Netflix or what have you.
In terms of feeling empty, again this is just based off personal experience, but my void gets filled when I work on the things I love most like becoming a better footballer and doing things of value in the meatspace. And living to provide value and spread love.
Just my two sats though!
