Create an image of a stressed and exhausted entrepreneur sitting at his desk late at night. His posture is slumped, with tired eyes staring blankly at a glowing computer screen. His face reflects burnout and depression, with dark circles under his eyes and a distant, overwhelmed expression. The room is dimly lit, with papers, coffee cups, and clutter scattered around, hinting at the pressures of overwork. The background is dull and cold, emphasizing the loneliness and isolation of his situation. The overall mood should feel heavy and tense, highlighting the emotional toll of burnout.
