Parenting and result directing

All directing books tell you not to be a result director. For example, you shouldn't say "act happy," or "now faster, with more feeling." Where do we learn result directing? My hypothesis: from our parents, and their number one result direction—"be careful!" Therefore, we parents should learn to give specific, actionable direction, for example, "slow down at Pike's peak because it's wet when it rains." My parenting thought for the day.
