This is me, boss comes in with a new task, I immediately whip out my green notebook and start writing as he’s talking then let him know I’ll get to it when I’m done with my current task. I use black for writing out the task and subtasks, red for crossing Xing items I’ve completed already, crossing out tasks that are no longer required, or writing notes that come up during the task (like ticket numbers). I think I’m like just below halfway through the notebook I started in February.
