"Follow your passion" is not that simple
I found this video of author Cal Newport discussing why he believes that simply telling somebody to follow their passion is actually a bad idea. It's an interesting look at how you need to focus just as much, if not more, on developing skills to excel at something as you do knowing what that something is. That you arguably can't even know what your passion is without striving to be the best at something, and the result of these actions is passion. Enjoy!
