Power is like love: once you experience the real thing, you can’t fully enjoy it without trying to share it with others.
When you’ve tasted true love, you want others to taste true love as well. The same is true not only of power, but also of wealth, friendship, opportunity, and everything else that has any value.
And that’s exactly how you know you’ve found something that’s worth holding on to. If it doesn’t inspire you to be more generous, it’s probably not the real thing.
