You are often the go-to person because you're always on the ball and seem to be able to get things accomplished on time. But unbeknownst to others, you may be going through your own personal struggle now as you try to balance your high level of productivity with your increasing uncertainty about the relevance of what you are doing. It's healthy to reexamine your chosen path, but you have work to do today so don't indulge too deeply in self-doubt. You can think about the bigger picture another day when you have more time at your disposal.
