The problem is that no one can measure what craziness can do

At the time you think it is crazy enough and you are out happily. Then .... it gets twice more crazy. Then you are likely, damn, I need to get back in. LOL... If in 1939, you tell others that Hilter is going to bring the entire world down, no one would believe you. For the same reason, never under estimate how crazy people can be. For that simple reason, you'd be better lucky than good. :-)

That is how Newton got broke.
