“My friend says the story is stupid and no one would want to read it.” That’s not real constructive feedback. If your friend has actual critiques of your concept, that’s one thing, but just saying something seems stupid is meaningless and carries zero weight. Don’t let people live their life and your life too. If you’re passionate about an idea, try it and see if it works. Worse case scenario, it fails, and you learn from it and get lots of practice for your next idea. Which still might be bad, but it will almost certainly be less bad, and same with the next, and the next, and before you know it, you have hundreds of hours of practice and experience and you’re creating real cool stuff. Also, sometimes ideas are good, but you currently lack the skill to execute them well. That just means you need to increase your skill level. An idea that fails badly when you first start out, might turn out fantastic 5 - 10 years down the road. Film directors/writers sometimes talk about this, where they had an idea or a script for a movie that they wanted to make, but they didn’t have the budget and necessary experience to do it justice early in their career. TL;DR Your friend’s “feedback” is worthless, if you’re really passionate about this idea, go for it. Worst case scenario, you gain a bunch of experience trying to make it.
