Not knowing what you want to do in life is a privilege.
Being a verb, not a noun. Constantly changing and developing. Your life being driven by your passions and ideas, rather than by one particular profession you chose when you were 18 not knowing a thing about how it will turn out. I think there is nothing wrong with that.
Okay yeah, if your dream is to become a doctor and help people than of course the only way is to get your years worth of education and save lifes. However, I find it amusing that you can be whatever the hell you want if you set your heart into it.
