Ask HN: I'm depressed because my ideas suck. Why am I so stupid?

I've been trying to enter the entrepreneurship game for about a year or two but I seem to be hitting roadblocks at each step. I feel like my pitch are just terrible, because everyone I've pitched my ideas to says that they're too difficult/risky or cannot be done because it works X way right now and its too hard to compete with some of the players in the space. Maybe I am naive but I've been trying to approach problems I have in my own life, seeing if others have these same experiences, and then trying to break down the problem into the smallest atomic bits so I can then figure out a "better way" in my mind. Side stepping a lot of the existing players by trying different things. However, it seems that the people I want feedback or investment from aren't willing to entertain alternative ways to do something. I feel like in many cases, the reason innovation is difficult or hard to do is because people try to go after the small gaps in the process,
