How do you prioritize tasks in your product marketing role to maximize efficiency?

I break down priority tasks on a quarterly, weekly and daily basis.

• Quarterly goals set the foundation for top projects and initiatives

• Weekly priorities map to those goals but are also broken down by urgency and importance

• Daily priorities map to the weekly goals but are broken down by the type of task (ex. messaging work vs. exec reviews) so to ensure calendar blocks for deep thinking, focus work, meetings

I manage closely to the calendar and reserve "blocks" to work through specific tasks. By assigning what will be accomplished during that time block, I'm able to map the time available to the task at hand
