I agree with your priorities. These are my missions:
Mission #1: End the Use of Carbon Based Fuel (Protect the Environment, the Aina)
Mission #2: End War (Stop wasting lives and money)
Mission #3: Make a backup of life on Earth (Just in case and learn how to live sustainably)
Mission #4: Find out how the Universe Ends and do something about it.
#1 takes most of my time. 
#2 I frankly haven't started on. 
#3 will teach us extreme sustainability, which we need to learn to survive here on Earth (when I say we, I mean most of the species alive today).
#4 I pay attention to every once in awhile. It's the dream of mankind. The answers may save us all.
