From my own experiences, I can tell tu that depending on the situation, Never Trying is much, much worse.
It depends on whether tu are más sensitive to humiliation, in which case trying and failing would be worse. o if tu are más 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 más 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 ^^
