Powerful people find deep satisfaction in seeing the positive outcome of their actions.
But I think they are even more pleased by seeing their actions amplified by others.
That's what makes them powerful: their reach exceeds their direct influence.
When you are inspired to do what your reference did for you, I assure you that makes him feel more powerful.
Learn to repay the kindness by committing to pass the kindness on.
That's a gift that can't be bought -- only given.
