A dictionary I once used defined power as the ability to produce or prevent a result. The OED defines it as the ability to do something or act in a particular way. People who have that ability are said to have power or to be powerful; people who don't have it are said to be powerless.
While my parents and then religion delayed me, I watched a baby sister and then a baby brother grow their power. I grew mine years later. I've taught social and political power to groups of people. Teaching it here is an experiment that might succeed or might fail.
Newborns are social creatures; they communicate. They first cry and soon chuckle, sigh or babble. First with facial expressions, then with sounds they say what they like or dislike. When my baby sister said "la la" the rest of us soon knew she wanted water. Babies soon learn the words their caregivers use and ask for what they want. They've started growing their power.
Asking for what you want is the stuff of Step One. You might not get what you ask for, but if you don't ask you surely won't. If you're not asking for it, an experience you enjoy might persuade you to start asking. My wife's first orgasm persuaded her. She wanted more and you can believe she told me so.
I've seen new born kittens and puppies as they tried to nurse. They didn't ask for what they needed; they wrestled for it. I hoped their mothers' bodies had anesthesia.
If I had grown up on a farm I might have seen struggles that would have curled my hair.
