Your priorities are allowed to change. There’s no point in wasting time trying to fuddle through something that you hate. If you wanted to be a doctor when you were a kid, it doesn’t mean you HAVE to be one now. Learn to do what you love and love what you do. As you work to discover what it is you love to do, you will also discover what it is you don’t like to do. Changing your mind doesn’t make you a quitter, it makes you actively involved in your personal decision processes—there’s certainly nothing wrong with that!
