There's no shame in trying and failing, but at the same time, criticism is a completely valid thing. It can, of course, be presented in a poor way, or it can just be poor criticism. But you don't have to be a professional opera singer to know that a professional opera singer gave a poor performance and there's absolutely nothing wrong with pointing it out.
If you're trying to entertain or inform me and you failed to do that, I will absolutely say that I was not satisfied with the result (especially if I paid for it!). Criticism is the only consistent way the world moves forward. We all need it in our lives. I don't know Mr. Roosevelt's context for that quote, but seeing it in isolation, it does not resonate with me at all. It sounds like a child trying to justify why they did win the race even though they came in last.
