We are the root of our own happiness. You personally know what you love in life and what you have passion for. If you can wake up everyday and look forward to what you have to do than you are doing it right. If you wake up and complain before you are out the door than you are doing it wrong.
Make a list of all the things you want to do in life. Then go do them. It really is that simple. If you have drive. If you have passion. Then you can do anything.
Take every moment of everyday to be the best at what you do. Put your heart into everything you do and the results will be greater than anything you do without passion.
