Here are some rules to improve prioritizing.
Prioritize early, prioritize often.
If stuff is a priority, do stuff. Don’t do other stuff.
If stuff is not a priority: don’t do stuff. Do other stuff.
If stuff is not done, but stuff is a priority, prioritize stuff over other stuff.
If stuff is done, but stuff is not a priority, prioritize other stuff over stuff.
If you cannot remember stuff that you think is a priority, it is likely that stuff is not a priority.
If you have made too many stuff a priority and you can’t remember stuff, prioritize prioritizing.
