I mean this is a really simple one, but it tends to fly over a lot of people’s heads.

Often when you’re writing something, whether that’s a situation or dialogue, you might think “Okay, what’s something people will find funny.”
Then you spend way, way too long looking up how humor works, what jokes are currently relevant (do not include current internet culture or movie references in your writing I swear to God), or you watch comedy specials to get ideas. And here’s where I’m gonna say how about you don’t do that.

At that point you’ll just be dissecting the frog, by which I mean you’ll understand how the frog works, except now the frog is dead.
What you should be focusing on is just as the title says; what makes you laugh?
The following is based entirely around my incredibly unreliable memory (Claire is a character written based on experience) so bear with me if I get a few words wrong.

I’m stealing this entire sentiment from Berkeley Breathed, who wrapped up Bloom County and then went about his life. Eventually he got a digital tablet and started drawing comic strips again, whereupon he found enjoyment in drawing Bloom County characters even after considering the entire thing finished. The reason he stated was:
”I made myself laugh.”

Really, that’s all you should ever aim for. But it doesn’t have to be restricted to just giving yourself an asthma attack because your genetics have determined “fun” is not allowed. You ever brought the mood to a crashing halt because while everyone else stopped laughing, you still looked like you’d been hit by pepper spray? Congrats you evolutionary dead end, way to make a joke into a potential tragedy, now where do you keep your inhaler?

If you’re writing, drawing, or throwing some music together, you should be the one feeling the strongest emotions as you do so.
Make yourself excited.
Make yourself tearful.
Make yourself angry.
Make yourself feel a bit of awe and longing for the fictional whatever you’re throwing together.

One of the greatest benefits to creating a piece of literature, artwork, or music is that others can feel the same emotions you did in the process of making it.

If you don’t laugh, then why should anyone else?
