Well I personally think power has so many responsibilities that there's too many to name, but some have to do with protecting your loved ones around you and making sure they're safe, fed, etc. others is balancing things in your life, like a work/ home schedule, trying to make good decisions that benefit for everyone, telling the truth to those below you, making decisions that some will not like, even though its for the great or good, and keeping a calm persona.
hope this helps a little:)
