Sales 101 really applies here. That fear of rejection needs to be overcome. This is especially true for something one or a few people are building for potentially hundreds or thousands or even millions. There is no way for those few people to completely understand the needs of many. You WILL fail. You WILL be rejected. It's not a matter of "if". It's a matter of how yo learn from those rejections and failures.
