You go to elementary school. Then middle, high, and you enter university. You get a bachelor’s degree, and then, amazingly not having had enough of school yet, you go get a master’s degree.
Now you’re closer to 30 than you are to 20, you’re just about as educated as education can educate you. You might think you would have a clue what you want to do. You might also think that you’ve spent a few spare hours, here or there, figuring out what you want to do with your life after school.
