Parents, career counselors in high school, and advisors in universities go on about finding your “one passion” and settling down with it, but let me give you a news flash. There is no one passion. It’s impossible. Our passions represent who we are, and no one has only one thing they’re passionate about. You may be a lawyer, but do you like cars? Do you like hiking? Can you paint or sing or enjoy teaching others? There are your other passions and each one of these can be made into a job if you enjoy them, if you’re good at them, and if someone’s willing to pay for them.
Essentially as humans (and I’m taking this huge guess and assume that if you’re reading this, you’re indeed human :)), our passion grow and evolve with us. What used to rock you boat and get you all excited at 18, might not be doing it for you anymore at 30. We grow, we change, we accumulate experiences and so our desires can, and probably will, change along the way. So stop obsessing about the right answer to what I want to do when I grow up, and instead focus on “what do I want to do NOW”.
