Balancing Serious Professionalism vs. the Cultural Push for Constant Humor: Does a "Sense of Humor" Undermine True Seriousness?

I often feel like there are two kinds of people in the world: one is logical and the second is illogical. I see many people admire those who have a sense of humor, but in reality, a sense of humor falls under the illogical category. That is why it can destroy people without warning—because if people always joke while talking, and nowadays everyone makes a habit out of it, it becomes part of their nature and they can't undo it.

They also teach others that they must have a sense of humor because it helps them handle difficult situations. But in reality, if someone likes jokes during serious situations, I don't think they are serious about anything at all; they are just waiting for someone to come and crack a joke so they can reward him.

Given how deeply ingrained this habit has become in modern communication and workplaces, my question is: How can I navigate a professional or career environment that heavily values constant humor without compromising my own commitment to deep, serious focus? Furthermore, does relying on humor in difficult situations actually help us, or does it ultimately distract from addressing core problems?
