“Like an archer who wounds at random” seems to suggest someone just shooting arrows randomly into a crowd with the idea that surely I’ll hit someone. Hopefully, this represents a wartime situation!
But the randomness of his actions wouldn’t seem to be terribly effective and is compared to “one who hires a fool or any passer-by.” Anyone who would hire a known “fool” or a random “passer-by” really can’t expect to accomplish much, either.
Good business practices are at focus here. It’s all about taking the time and effort to do something right – like making deliberate choices to find and empower right people – even the best people.
We all want to work alongside folks we can trust and count on to be there. That doesn’t happen by capricious random acts, but is the result of taking time and making tough choices to do the right things.
