When you do good things and when you do something in the right way, people get jealous of you. Jealousy is in the eye which compares itself to the outer world.
The most common jealousy is in the power games. People with high authority and powerful position are those from whom the rest of the world get jealous.
Everybody needs authority to be decisive in his actions and unless people get some kind of authority, they keep feeling jealous of all those who hold the power to authorize.
But only power and authority are not that matter. Your good deeds also matter a lot in order to make people jealous of you. You should always keep doing the goods things to whatever level you can and leave the rest to be settle down itself. Don’t worry and keep doing good.
And if you avoid the jealousy factor at all, then it is always better to keep yourself as low as possible. The less you advertise yourself, the less amount of people will get jealous of you.
