I've learned to think in terms of having a long career. Actors can have very long careers that last until the day we die but there will be moments when you'll feel like you're a failure or when you're disappointed in yourself.
And time itself? Time was a never-ending medium that stretched into the future and the past - except there was no future and no past but an infinite number of brackets extending either way each bracket enclosing its single phase of the Universe.
