in 5 years

When asked how I see myself in 5 years, all I could think of was me in a room with really great natural lighting. I am doing something creative, but I don't know what it was.
I've always done what comes to me. From my choice of high school, then going to BYU, and now working at fred flare. It was just me doing what came. Those things aren't coming to me anymore, and I feel like now its up to me to bring on the next phase. It would help if I knew what I wanted, only that is the hardest question anyone could ask me. What do "I" want. How do other people know what they want? How do they pin their careers or education on one choice? One moment where they say "and then I knew"?
