Standing in your own power means to speak  your mind without fear of persecution or what someone else might think. It really means to just "be yourself".   It seems like a simple concept, but one of the hardest things to implement.

We are not as many years "old" as people say; we are 9 months older.  If your birthday is today and people say you just turned 10 years old, then correct them and let them know they're wrong.  Unless you were born premature, you are technically the age you say you are PLUS nine months because once you were conceived in relaxing in your mother's womb, the clock was already ticking.  That means when you turned the age of 10, you were already almost 11 years old.

Take yourself as you are right now, whether a teenager, young adult, middle-aged person, or senior. Ask yourself, if this version of you could spend one afternoon with yourself when you were a child, what would you tell your child-self? What advice would you give about life in general?

Education is fatal to stupidity.
