Up and through college, it seemed to me that the ideal thing was to know what you wanted to do with your life and then head for it. “What do you want to be when you grow up?” is a question everyone gets asked, and when you give multiple answers, it somehow seems less ideal than a decisive, “I want to be a dentist!”
The truth is, no matter how passionate you are about your chosen field of study, it won’t be enough to satisfy you. Creative people in particular need variety to grow on and inspire their work. Screenwriters will tell you that you can’t just be a screenwriter—it’ll sap your life energy. Variety really is the spice of life.
If you know what you want to do, by all means, go for it. If you don’t, then experiment. And even if you’ve found your calling at this point in life, take a break to pay attention to your hobbies. You’ll be better prepared for whatever it is you’re made to do as a Person of Many Interests and Talents.
