If you find something that works for you that lets you create artifacts of your interests, go for it! You never know what people will latch on to.

I also have a lot of unrelated interests and ideas for projects I lack the depth to get off the ground.

The real breakthrough for me occurred while I was using Minecraft to practice improvisational comedy on YouTube and realized that I can take any infeasible idea that would never happen like "What if I gave a $40k speech to Goldman Sachs?" and added "... in Minecraft?" to it.

I made a lot of videos people didn't get for about a decade, and now I quit my day job as a LAMP dev and make most of my living off tips from viewers.

Best of luck!
