Finding your dream job requires more than just hoping the stars will align in your favor. You probably have a better chance of winning the lottery than having the job fairy deliver you the perfect job just when you need one.

Perhaps a teacher suggested your current career path, or maybe a job simply opened up just when you needed one.
