If we want to know whether we are successful or not, then we have to ask ourselves: Am I really getting better off compared to my previous stage, not compared to somebody else? Am I now better off compared to what I used to be? After all, my restlessness is the reason I strive so much. Am I less restless now, or is it so that the events that I quote as my accomplishments have actually made me more restless, more frenzied, more feverish, more insecure?
If you find that your achievements are in fact making you more insecure, then they are not an indicator of your success. You are not quite mapping your route rightly, and that has to be very clearly known.
