If you do find yourself with your current job is really that giving only a few amount of salary and you've been jealous into those who are sitting on good positions or jobs then it will really be just that stress you out because you will be just that definitely be trying out achieve on what they have committed or attained. Speaking about job then it will really be that different to each other and better focus with your own progress and achievement rather than making yourself having this kind of situation on getting jealous.
I am jealous of people who don't suffer from work-related stress and of those who really love their job, waking up and feeling good about what they do on a daily basis. It's not as easy as it seems.
