A non-doer is very often a critic-that is, someone who sits back and watches doers, and then waxes philosophically about how the doers are doing. It's easy to be a critic, but being a doer requires effort, risk, and change.
To sit home, read one's favorite paper, and scoff at the misdeeds of the men who do things is easy, but it is markedly ineffective. It is what evil men count upon the good men's doing.
People want to see the car crash instead of the race. But, when you're the one in the car that's crashing, it's not much fun. I'm enjoying the race.
Don't live life as a spectator.
In the West, people tend to look at life as spectators, but in the East, people are the thing.
Thus I live in the world rather as a Spectator of mankind, than as one of the species, by which means I have made myself a speculative statesman, soldier, merchant, and artisan, without ever meddling with any practical part of life.
