Dreaming of a bench mean you are currently slow at completing your task, and you tend to do whatever you can to avoid it. What causes you to be slow is that you are not really focused instead you dread every second of it.

From today on, jump into the game, engage yourself knowing that everyone is imperfect and everyone makes mistakes. Push forward.
