For example, from my point of view, in all jobs the most important issues are the working conditions, the salary and the type of work that you have to do. Other element that I consider very important is the work environment because If you have a good job in terms of salary and work conditions but the work environment is bad, you are not happy at work and the other basic terms take second place. The essential condition that your job must satisfy is your happiness!!
If you are married or you have children, the free time and the flexible schedule are most important than a good salary because you need spend more time with your family. On the other hand, when you are young you rate more the money than a good schedule, free time or duties because you don't mind about work more hours.
Finally, the characteristics that a good job must satisfy depend of your personal situation and your aspirations.
