Go ahead and say what they are if you know them. I doubt you will be able to say anything. Instead of being silent, you should have the courage to admit you don't actually know what you're talking about and don't have much if anything to tell me.
Except when you are being taught by another person, all new knowledge comes from your own observation, trial and error. When you are learning from another person you are learning about the aggregate of incremental failures that they made, finally leading up to a success. Very rarely do things totally succeed on a first attempt.
How can you possibly say failure can't be useful? How do you iterate your plans and designs? I don't think you appreciate how knowledge works. Your weird demonization of failure (including it somehow being a moral issue?) won't force success, it's just going to stop you from realistically evaluating your goals.
Aside from that explanation, I'm not dying to debate you or list exhaustive examples or whatever because you're belligerent and arrogant. People like you can't be convinced, you have to go through it yourselves several times to figure it out, if ever.
You need to double check your interpretations of what I said. If you fail, you fail. If you treat it as a good lesson and learn something from the result, is that the failure making you learn or is it you?
Aside from that, you have described yourself in the remainder of your comment's criticism of me. Go ahead and check out of a real conversation with me even though you don't know a single thing about me. You've already done all the damage. People in the present might be fooled by your pretense to humility and ability to diagnose arrogance, but in the future people will look back on our comments and find it very easy to discern that you don't even know yourself.
