I heard two comedians discuss how they came up with humor bits. One said he kept a pocket-sized notebook and a pen with him at all times. If a potential comedic idea or joke passed through his head, he wrote it down.
The other comic noted that “I write down anything funny I’ve just seen or heard. Maybe I can’t do anything with the material right then, but at least it’s an idea-starter.”
Are you in the newspaper or magazine or content-development business? If so, the “notebook idea” might be worth thinking about. The thoughts you develop might be serious or historical or comedic. But capturing the idea as it races through our brains is important.
And since most of us carry cell phones, we can simply speak the idea we just thought about into the phone’s memo function.
