Okay, I'm quite sure my question has been asked before, but I didn't see anything in the past threads....
So...
I've found quite recently that when I get a really good idea-- you know, the ones that really explode in your brain and you find yourself saying "Ooh, this is SO awesome!! It'll totally fix *insert annoying problem here*!!!"-- the euphora of it is dimmed by this cynical, scared voice in my head that says "I can't do this. I can't do this. I don't know enough. I haven't learned enough." And the Good Idea takes a metaphorical nose dive, becoming not near as good as I know I can make it. Every time it comes I tell it to go back to the dark corner where it came from, but it gets more insistant. Any tips on how to get rid of it?
