What are your criteria for idea filtering?

I always have a lot of ideas for things to build and problems to solve, some small, some big, some realistic, and some straight up silly. I've always just written them down in notes—I strongly believe writing every idea down, no matter how bad, inspires more ideas in the long run—, but lately I've been wanting to rate ideas along certain dimensions, just to have a coarse overview of what kind of ideas I come up with, and which ones may be worth pursuing.

My question for you is: do you have any criteria for idea selection, and what are they?

I'll start out with the simple ones I've got currently:

• Goodness: Is it something that will add genuine value to the world, and not just be profitable? Something that will give me a warm, fuzzy feeling in my stomach?
• Profitability: Is it something I can make a living off?
• Difficulty: How hard is it to do?

I'm looking forward to hearing yours! 😁
