I graduated from college at 20 and became a tech investment banker. In hindsight, it was a terrible decision but I simply didn't know any better. Tech crashed in 2001 so a lot of my engineering friends went into finance and I simply followed them. I learned two really valuable lessons from the experience: one, if you don't build your dream then someone else will hire you to help them build theirs; and two, I learned what really mattered in life after I lost it all from working all the time. Hint, it's not money or fame.
