Power
Today I read a book about power. After reading, I have a more detailed and conceptual perceive of power.
What is power?
Power is generated in the interaction between people.

You have power over one when you can let one do what he won’t do without your instruction;

You have power over one when you can let one not do what he planed to do.

Power is an ability to either harm or benefit.

Power is the influence in the process of making decision.

You lose power when you have to compromise what is less valuable in order to protect more important interest.

You lose power when you only have one source to turn to.

Yes, power is an uneasily defined concept. There is nuance between power and authority and leadership.
