Thought versus action

"There is however, a second objection to the philosophical life, and that is reflection tends to decrease action. In other words, the more we think about things the less we actually get done. As Hamlet soliloquized:

And thus the native hue of resolution
Is sicklied o'er with the pale cast of thought.

This reminds me of the famours Monthy Python sketch, where a team of German philsophers play a team of Greek philosophers at football. When the whistle is blown to start the match, instead of kicking the ball, all the players walk around, stroking their beards. Such is the stereotype of the impractical philosopher."
