Where you come from is equally important as where you are going to.
Setting up your short term or career goals is a very thoroughly discussed topic and I’m not going to elaborate it now. You can find some hints about it in my previous posts. Much more in all HR web sources.
I was occupied by the fact that I was very often unsatisfied with things that most people are very happy with. And yes, it might be because I’m snobbish or because (I think) I set extremely high goals for myself, but instead of indulging myself with labeling, I have figured out that this is much more related with previous experiences then personality. Personality plays a role of course, but experience is what sets our benchmarks and creating our idea of happiness and satisfaction.
