What is failure at life? Everyone could do much, much more than what they did, and almost everyone has done something, so by your criteria, everyone has failed at life. Not freeing a country from the repressive rule of the British Empire, inventing an awesome goddamn flavour of ice cream, or discovering the latest method of getting a killer orgasm doesn't make you a failure, because those people could have freed two countries, or invented two flavours of ice cream, or invented a way to have sex with zero risk of pregnancy not involving surgery. But my point is, everyone is a failure, or no one is a failure, depending on your world view. You can't set some sort of quota or time table for this sort of s**t.
