The Truth Apparently

Yesterday me and my father were talking about jobs. I've told him that I've been applying to jobs that deal with animals but haven't had luck yet. Its been 3 years of searching but I do believe eventually I will. But my father came out and said that my dream is unrealistic. At my brother's graduation from college there was over 100 people who graduated from animal care. I dont have a diploma. I've done animal courses online and I have my pet CPR. My father also said that most people have jobs that they hate and will never get there dream job. All my family except my brother have always complain about there jobs. I do hope that i find a job i will like.
