Think Several Ways

It's simpler and more efficient to be one person, have one set of values, treat people one way. But it doesn't work. People and situations are best treated differently - ideally, every person and situation must be treated in its own individual optimum way. This is silly - who can spend that much time thinking? Neither a single approach, nor a multitude of approaches are best - perhaps merely being aware when your single approach has failed, and you should not use it, or at least modify it, is enough?
