J is for jealousy.
There's all kinds of jealousy out there. You can be jealous over the clothes someone is wearing. Jealous over a person's house or their job. You can be jealous over how much money or a job one has.
We all have jealousy hit us at some time or another. I am guilty of this from time to time.
One thing I can say that I have become less jealous of is other people's jobs. Why? Because I love the job I have. I love my boss.... so I am not jealous Joe Blow has a great boss. Why? Because I am my own boss.
