I have a notion setup organized around tasks, calls to organize, and clients.
I have several view and attributes to fit the tasks to my workflow.
I have a daily routine and a weekly routine template that gets added to the task list regularly with custom views for each action. This includes reviewing the email inbox, the calendar, the long-term backlog, and many other things. I then end the daily routine by estimating among the open tasks, the most important and setting a workload for the day.
