You don’t really “get” power. You align yourself with where it is.
In personal life, aligning with power means allowing your genuine desires/will to move you. When trying to force something that is not real, you are powerless.
In politics, aligning with power means channeling the will of the people. You get elected when you represent what moves them. This is why politicians must have an keen sense of the mood of their base and play into it.
Move to where power (energy) is and you have it.
