My To-do list

Somewhere between work and leisure lies my personal to-do list. It does not appear in my gmail, or on a note pad somewhere. This list, my platinum list, is in my head.
I do not visit it frequently, but gladly add onto it, neglecting that i am 1 person and there are only 24 hours in one day. Before you know it, on a lazy day, i take out my platinum list, scroll through it in my thoughts and wonder how did a tiny list grow so big. Looking at the time left i shudder.
