Sunlight streamed into Mark's apartment, illuminating dust motes dancing in the air. He stretched, a grin splitting his face. The air itself seemed to hum with potential. He grabbed his favorite tie, a bold swirl of colors, and hummed a nonsensical tune as he knotted it.

He imagined the office buzzing with anticipation. He imagined the corner office, the view of the city, the prestige. A mischievous glint sparkled in his eyes. He poured himself a giant coffee and winked at his reflection in the coffee maker.

At work, he made sure to greet everyone with an extra-enthusiastic, “Good morning!” He found himself offering unsolicited advice to several colleagues, each comment delivered with a lighthearted jab and a wink. He felt a fizzing energy under his skin, a need to move, to create, to… well, to win.
