One of the best things about having a job is that no matter what you do, you will always get paid a base salary. The longer people stay at their jobs, the longer they understand this “benefit.” Managers understand this as well, which is why they are constantly looking for new blood to keep the workforce hungry.
Everybody knows somebody at work who just kicks backs to your chagrin. Despite paying their dues way longer than you, you’re still annoyed that s/he is more senior and gets paid better! Some people are stupid enough to have the mentality of, If he can do so well slacking off, then so can I! Pretty soon, your delusional self starts getting bad marks in your mid-year review, doesn’t get a raise, nor do you get a promotion.
The lack of congruency is what gets people in trouble. Thinking we deserve one thing, when we really deserve another really kills happiness. We start complaining about perceived injustices, when we really have nobody to blame but ourselves. I remember being so mad at losing a tennis match, all I did was mentally blame him for “pushing” the ball back to me. The reality is, I was not in shape and could not maintain my level of performance for the entire battle.
