Surround yourself with positive, talented people to keep your mind clean.
Hell even vogue and trash mags call out 'energy vampires' (lol) but it's all the same thing.
I legit decided to not listen to gangster rap in the 90s because a dude said to me 'that shit will warp your mind ' but I realized all music and influences do that.
So books it was...god I was a nerd!
I cut the cord on much of it early on, mostly because the value was terrible (aka music industry in the 90s was just bad value).
Now it's the odd anime that had a deep story that pulls me in...and lectures..Holy fug I love watching smart people talk :)
