Dominion over all things doesn't come with age, spirituality, or even gratitude. In fact, it doesn't come at all. You were born with it and you use it every moment of every day, whenever you say, "I will... I am... I have..."
And for that matter, whenever you say, "It's hard... I'm lost... I don't know..."
So, be careful where you point that thing!
Life is not about learning to find your power. It's about learning to use it.
