I actually think having ideas and talking yourself out of them, as you describe, is completely healthy.
The ideas that keep coming back to you and have to be repeatedly beaten away are the ones that might be worth taking a chance on. Pay closer to attention to the ones that keep coming back.
Yes. Coming up with bad ideas is easy. It's important to have a good filter. In general, I think creative people begin many more projects than they finish, and often it's only once you get into the project a little that you can tell it's not really that great.
That said, in your case it might be worth taking one of your ideas through to completion just to have the experience of doing that.
On the other hand, I think it's also important to actually keep MAKING things, even if the ideas aren't yet amazing. It'll give you the knowledge and the self-confidence to tackle the really good ideas more decisively when the time comes.
Choosing small projects that can be finished before you get too bored or distracted can be a good way to do it.
Agreed. I spent years thinking of ideas and dropped many of them because I felt they weren't good enough. When one hits that is good enough, don't stop, just do it.
