A mission statement is not a gesture of strength and focus but a letter of surrender.

It’s implied that we want to be the best and dominate.  Natural selection already provides this non-verbal mission statement and everybody knows it.

The only reason to have a “mission statement” is to communicate a focus that is other than the natural implied one of being the best and dominating.

It’s either a lie or a surrender.   Either way, it’s weak as hell.
