You may hit a wall today. That is, whatever you are trying your hardest to accomplish could reach a climax of some kind. Maybe you will break through, maybe you will break down. Be prepared to meet the challenge or the celebration with a steady grasp on reality. Be especially attentive to your needs while you work: drinking water throughout the day is a must. Examine your desk chair and computer set-up. Is it ergonomically correct? These kinds of considerations will steer you toward greater awareness of what's to come.
