Power is something you assume to tip the scales in your favor. It has more to do with privilege and advantages than strength, always needing someone to oppose or compare yourself with to really matter. Power, you can buy and sell. You can be without power and still bear yourself up with strength. Strength is all you and has nothing to do with what it gives you over another person. That, no one's ever been able to bottle and hand out. Not even me.
