How do you go about prioritizing your subtasks, or your ordinary tasks for that matter, when it comes to tasks that almost has flow-chart types of actions?
For instance, I have to do these in a specific order but not necessarily in a specific space in time;
Main task: Go visit grandma
1: Get car
2: Take care of laundry
3: Pick up sister
5: Eat at Route 66
7: If grandma has forgotten anything, shop at the local store
8: Drive until we get to grandma's house
Any suggestions as how to manage situations like these when they are truly linear if nothing unexpected happens would be great.
