One reason I like the big cats so much is that they seem to have so many moments when they just exist in their own power with nothing to prove. They are watchful, playful, quiet, loud, gentle, or fierce — all as and when they want to be. And, if they have their moments of quiet and gentleness, that doesn’t take one jot away from their power. In fact, it enhances it.
So much of this is projection & anthropomorphism, but the lessons hold.
When was the last time you moved through the world feeling powerful with nothing to prove? Go be the tiger.
