But Which is the 20%?

You know the 80/20 principle says that 80% of the value comes from 20% of the effort.  (Unequal distributions like this are a pattern, not a law – sometimes it is 70/30 or 95/5.)

But which is the 20% that you should do, so you don’t “waste” your effort on the 80%?  Which is the critical few that merit your attention in a new-to-you situation? I can almost always spot the critical few in the rear view mirror, but only occasionally looking forward. In new-to-you situations, you must experiment and push forward and apply what you learn.  This is the price of adventures and meaningful work.

If you’re in a situation which feels familiar – either through personal experience or you’ve recognized it from the experiences shared by others – you have a better shot at identifying the critical few, and the levers to move.  You can avoid that which you know is ineffective, or a side-show.  This is the payoff from reflection, study, and applied imagination.
