Humor is for the most part nothing more then a human emotion. It isn't something you learn but something as much as it is something you learn to express. You could however learn to become a comedian.
The telling of the joke (delivery) is as much of the actually joke as the punchline within the joke. Its an art form to deliver the joke in such a way that taking some so mundane and unfunny and turning it into a very humorous story/joke. By the way, some of the funniest people in the world consider themselves "unfunny" and that is what makes their humor so much funnier.
Comedy is all about timing, or in rare occasions... the lack there of. When I was young, I wanted to learn how to be funny. I was advised to take an Improv class.
en.wikipedia.org/wiki/Improvisational_th... Depending on where you're located, you can most likely find classes at any continuing adult education centers or colleges. I would just type in "improvisational theatre" with your location into your browser and see what you can find! When I took these classes, I learned not just comedy but many other tools that I continue to use, such as brainstorming and working as a team.
Improv also helps to keep that imaginative part of your brain working, while being in the moment. I believe it can teach you great comedic skills that you'll keep for a long time. Just build up the nerve to sign up for one of these classes.It's not as scary as it sounds, plus you might make some friends for life!
Here's a video from the Groundlings which is a great comedy improv group.
I love to make people laugh and hope to laugh every single day of my life. I think it's the way you see a situation that makes it amusing, its "mindset" and takes years of practice to become so twisted. LOL.
I think you can give yourself an edge by learning more about humor and comedy, studying other bits, perfecting your timing, using a mirror, recording yourself, trying out jokes on other people, etc. But you can never completely make up for natural humor talent. Some people are just funny out of the womb.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
