According to the gemara (yesterdays daf Berachos 43b) you should be. The gemara states the following:
מלמד שכל אחד ואחד יפה לו הקב"ה אומנתו בפניו
ואפילו בורסקי נאה לו אמנותו בעיניו ועשה הקב"ה כן שלא יחסר מהעולם אומנות
The gemara states that hashem created every person with a job in mind, and as Rashi explains even a בורסקי who deals with smelly carcasses all day should get satisfaction from his job because hashem made him that way so that there would be people to do every kind of job.
You see from the gemara that a person should work at a job that he likes and gets satisfaction from. This doesn't mean that a person should be defined by their job, but it does mean that a person should not hate/dislike their job. You see from the gemara that it is not 1 size fits all but that every person is different and therefore every person needs to find the right job for himself.
