> There's an embedded ambiguity in your sentence in that there are two kinds of failure. Fair enough. In 2008 somebody asked me if I wanted to try cocaine. I didn’t. He eventually moved on to heroine and his life is now utterly “failed.” in the worst sense. My life is good. In 2013 somebody told me I need to buy as much bitcoin as I can. I didn’t. That guy is now a billionaire and I’m still an average dude. Personally I see those two situations as basically the same: decision -> outcome. There is a continuum of outcomes and the “fail” end could be really catastrophic, for you, your finances, your life, loved ones, possibly even the whole planet in the extreme.
