I have a fairly strong knowledge of seemingly useless information and a collection of seemingly useless stuff.
Does the majority of culture think it's important to know who created the character of Wonder Woman and why this character was created? Probably not, but I do.
Does the majority of culture think it's worth purchasing action figures and a Batman mug and having them as show pieces in his office? Probably not, but I do.
The information and stuff that many consider garbage I consider gold, because they are where I turn when I need some creative inspiration and imagination.
I think about a specific shot and line from an old kung fu movie, I look at the packaging and costume of an action figure I love, I take a sip of coffee from my David Bowie mug while I'm leaning back in my chair listening to an 80s post punk track, and all of that information combines to produce something new, something unique, something interesting.
This stuff and information that many people would say is useless? It isn't. The expert sees this stuff and information as something useful; random bits and pieces of content, aesthetics, ideas, and sounds that can all be integrated to produce something powerful and unexpected.
Look around you right now and consider the objects that make you smile and bring you joy.
Think about that movie you watched that you were afraid people would call you a nerd if they knew you watched it.
Reflect on the things that you loved as a kid and why you loved them.
Then think about how all of those little creative dots might connect.
I find that doing so usually produces something pretty amazing.
