Never take your position for granted and never let any favors you receive go to your head. - Robert Greene

We humans are naturally compelled to compare ourselves with one another. We are continually measuring people’s status, the levels of respect and attention they receive, and noticing any differences between what we have and what they have. For some of us, this need to compare serves as a spur to excel through our work. For others, it can turn into deep envy—feelings of inferiority and frustration that lead to covert attacks and sabotage. Nobody admits to acting out of envy. You must recognize the early warning signs—praise and bids for friendship that seem effusive and out of proportion; subtle digs at you under the guise of good-natured humor; apparent uneasiness with your success. It is most likely to crop up among friends or your peers in the same profession. Learn to deflect envy by drawing attention away from yourself. Develop your sense of self-worth from internal standards and not incessant comparisons.

Your days are numbered. Will you pass them half awake and halfhearted or will you live with a sense of urgency?
