I don't like watching internet videos all that much, but based on the title I have to strongly disagree. I allowed myself to be swayed into not following my passion for reasons of practicality during undergraduate school. It was a terrible choice, and I was miserable, despite making more money than most of my peers. So I quit, went to grad school to really do what I wanted, and now, life is awesome. My advice is not just to follow your passion, but to do so in a way that makes monetary sense. Or, figure out what you love, and then figure out how to make money doing it. It's simple. If you can get up everyday, and be excited to get to work, you've made it in life. Not saying my job is always fun in the traditional sense of the word, but I overall love what I do, and I'm doing what I always wanted to do as a kid. It's awesome, and I recommend that strategy to anyone who wants to be happier.
