How we change what others think, feel, believe and do
Although there are many different types or power, there are a number of things that may be considered which will increase the power you have.
The Scarcity Principle makes anything that is not easily available more desirable. If the power I have is something that other people do not have, then I am the only wielder of this power and hence I can choose how it is used.
If what I have is more desirable, then I can make greater demands, asking more for it and so on.
A negative form of this is where my power is undesirable, such as the power to punish. Again, the greater the undesirability of my power the stronger the power is (although it will create very different reactions to a positive and desirable thing).
Some people have power but are not good at wielding it. Like a swordsman with a sharp cutlass, a skilful user of power uses just enough to get what they want and no more.
If my power has a great impact on people, then they will pay greater attention to it. Thus a bank robber acquires great power (and money) from the use of a gun.
Sometimes power costs a great deal to acquire, such as expert power, for which takes time and money to get through college.
Power, when used, may be used up or it may retain its 'full strength'. Thus when a teacher shouts at a class, it will only work for a while and if they keep it up, before long the children will ignore the loud thing at the front of the class. A good teacher only needs to hint or raise an eyebrow.
So not only build your power, but also make it scarce, desirable, etc (as above).
