However, I would like to go a bit further and propose that power is a pretty profound concept that is closely tied to the meaning of life. I will now proceed to express some ideas I have developed about the nature of power and how it's tied to a meaningful life.
To me the meaning of life is development. We should constantly develop ourselves, learn more, acquire more resources, so that we can influence your surroundings and gain control of your own mind and desires. Either a man determines his own fate or others will determine his fate for him. You have to have desire for life. In my view, this is exactly what Nietzsche calls POWER. Power is simply a being's ability to influence it's internal and external reality. Every living being has power since life itself is power - plants reach out to sun and drain water from the soil because they too have will to live, they too have will to power. They want to spread and fill the earth, just like we do. As long as your heart beats, you have the potential to influence the world, you have power, but when you draw your last breath, you no longer can affect your surroundings. Therefore life itself is power.
All relationships are based on power. There is no unconditional love. A mother loves her children because the child satisfies a need that is based on power. Acts of self-sacrifice and self-denial are not really selfless, because they're motivated by moral values or evolutionary motives that are also manifestations of power.
