Seneca, Moral Letters, 114.24: "A king that is....an uncontrolled, desire-fueled, over-indulged soul is turned from a king into that most feared and detested thing--a tyrant."
Absolute power corrupts absolutely is a common saying, but doesn't always have to be true.
How can we use stoicism to be better leaders? Increasing our inner strength and self awareness, what we value and how to limit our desires is something that should be revisited over your successes in life. As your business grows, or promotions in your career, you should take the time to determine how best to use the power/leadership opportunities you have. A good leader will not leave a trail of destruction as they get promoted (I don't believe many people purposefully do this, but if you are not aware that this can happen, it might actually happen without you even trying), but improve the office/station they are in so that the future successor has the best chance to improve even further. You must create and environment where there is a runway for improvement and enthusiasm to make things better. A good leader would be proud of this, and will continue in each part of life they grow as individuals.
I think everyone would like to think in whatever position they are in that they function as a desired philosopher King and not a hated Tyrant.
I think today I'm going to focus on measurable changes I can make in the leadership positions I am in for the person that will come in that position after me. I will consider it a success if I even find one or two impactful changes!
