The old desk creaked as Daniel pulled out the drawer, a cloud of dust puffing into the air. He was searching for a missing tax document, a task he loathed. The unexpected discovery of a letter, however, immediately brightened his mood. His younger self’s handwriting, so neat and precise, felt like a message from a different person. He felt a light, bouncy feeling.

He unfolded the paper, a faint scent of old perfume clinging to it. The letter was addressed to his future self, a prediction of sorts. “Dear Me,” he began to read, his voice becoming increasingly boisterous, “I hope you are having more fun than you are having right now, because frankly, this is boring."

He began to laugh, remembering the dreams and ambitions that had once filled his young heart. He felt like he could do anything.
