"Keep looking below surface appearances. Don't shrink from doing so (just) because you might not like what you find."
"If it ain't broke, don't fix it" is the slogan of the complacent, the arrogant or the scared. It's an excuse for inaction, a call to non-arms. It's a mind-set that assumes (or hopes) that today's realities will continue tomorrow in a tidy, linear and predictable fashion. Pure fantasy. In this sort of culture, you won't find people who pro-actively take steps to solve problems as they emerge. Here's a little tip: don't invest in these companies.
