Founders

Talking about our ideas in premature stages decreases their chance to turn into reality. I've learned this the hard way ngl

I see your point, but in my experience, sharing ideas early often brings valuable feedback and collaboration, which can actually help turn them into reality more effectively.

In my experience people dilute premature ideas with their own very quickly. But they have productive input on well thought out plans.

I agree to some extent, but I'm confusing...
Could you share with me how you can know if your idea is good enough to work on? I'm asking because I know that many people have to stop their projects after a few months of working on them, which wastes a lot of effort.

By failing many times I guess. 
I think you'll never know until you give it all you can before giving up on it.
If your idea is actually novel, most won't get it at first anyways.
