In my opinion, the entire field of investment management, involving hundreds of billions of dollars, would be more satisfactorily conducted if everyone had a good yardstick for measurement of ability and sensibly applied it.
Those who consider the inessential to be essential
And see the essential as inessential
Don't reach the essential,
Living in the field of wrong intention
There should of course be left a field of work for the sake of experiment but at all times one must remember that there will always remain open a possibility of err.
