In my opinion, I think the statement means that if You don't like what job You chase, You should change it, because, for example, you're a teacher and if You don't like this job, You could Be rude with your pupils, and if you're ungrateful about your life, You don't have to Be angry on your students. If You don't like the job You choose, You do everything wrong and You can't concentrate. If You like to pe a cop, I think You should Be a cop. You must have at least 3 jobs on your mind, and see where You can apply. And if You don't took the job, don't Be dissapointed! Something special is put for You. Good luck with choosibg the right job!
