From my own experiences, I can tell bạn that depending on the situation, Never Trying is much, much worse.
It depends on whether bạn are thêm sensitive to humiliation, in which case trying and failing would be worse. hoặc if bạn are thêm sensitive to regret, in which case nnever trying at all would be worse.
For me, I'm not easily humiliated and my ego would be thêm dented if I didn't try at all, because I am one of those 'what if' people who like to just go for it. LOL – Liên minh huyền thoại ^^
