well, I'll never forget Carlos Santana answering what is needed to play the guitar well. "Cabeza, corazón y cojones" Brains, heart and balls. I thought that was for anything in life too.
I don't understand what is the connection between creativity and power... of course I agree truth leads wisdom (even the "sad truths"), and love leads to joy (and hate to the oppossite), but I don't see why creativity leads to power/strength. Courage should lead to strenght and power.
