I didn’t have a career. I just did the next thing on the list. – Neil Gaiman, “Make Good Art”
Unless you absolutely, positively know what you’re meant to do at the age of five, you’ll find yourself on a meandering course. You may have a general sense of direction, but you probably won’t be sure of the way to get to your final destination. You’ll think about things like internships and entry-level positions, some of which will get you closer to where you’re trying to get and some of which will lead to dead-ends and course corrections.
