You're describing most people. Most people (99.9%) can't come up with novel ideas either. They just follow the latest trend. Art, marketing, music, etc. If you've spent any time in the creative spaces, you'll realize most people don't really have much talent. Skill, sure, but that only gets you as far as someone else's latest idea.

Honestly growing up, I always assumed everyone could be creative. Until I started asking people to randomly create a name for a fictional character.

Blows my mind how many people won't or can't do it.

I still get anxiety thinking back to picking a gamer tag or email username and not coming up with anything original despite unlimited options.

Its hard to be creative without any constraints.

Never understood that. Until I witnessed exGF sweat bullets trying to do them same. You're not alone.

Group of friends I grew up with would challenge each other to say nonsense or make random lyrics to songs. NO clue it would actually turn into a creativity skill. Give it a try.
