In all honesty you won't learn a damn thing reading that "bozo like the sky because it's blue" type of conversation, YOU have the creative mind and the only ideas that matters are your own, don't be afraid to be original just because some illiterate caveman didn't give you his approval, keep in mind that you're not doing the one and only work of your life, as you are a creative person (as I believe) and you'll make a hundred more stories, some of them will get more popular than others but it's not what matter.
the one only thing that matter is that you get to work, create stories and give them to the world, use that bottomless well of your imagination to create as much as you can until you die.
