Everything seems to have been done already, what is there left for me?

Short answer
Look a little bit to the side of what you are staring at.

Long answer
Even if you walk a hundred miles along an endless road, you still have an endless stretch of road left to walk. When you discover or invent something, it often appears obvious and simple in hindsight. The present works like the blind spot in your eyes, it can only be discovered if you look a bit to the side of what you are regarding. Good inventions are sprung from actual needs, thus it is more interesting when you made the discovery than what you discovered.
