Sometimes too much contemplation, religion, conspiracy and whining and not enough pragmatism and doing.
That's why I mentioned too much of one and not enough of the other. People who spend all their time contemplating and whining are sheep in a way also, even though they may not realize it. One can be socialized into being a sheep thinker do-nothinger by some religious or ideological figurehead.
In the Beatles' Yellow Submarine movie, there is a scene where someone is trapped inside one of those bubbles. One character is on the outside preaching all of this theoretical crap about the bubble and how to supposedly solve it. Another character says, "Somebody just crack the thing open with a hammer", which they did and it solved the problem.
