Do you think that in general people are satisfied in their current jobs? What can you do if you want to change it?
What does it mean to be satisfied with your work? The first step is to determine what is the motivation of each person, there are people who are satisfied if their work is close to home, there are people who are satisfied if they have the opportunity to work in a company where they can travel, and so there are many motivations even salary (but beware, it is the most short-term).
So based on your motivations you should be able to answer if you are satisfied or not, you can not generalize at this point.
And if you are not, move, inform yourself, talk and listen to people in your sector, your functional area, family, friends and from there look at options in the market that are aligned with your motivations and change, but change, the Time is the most valuable resource we have.
