Sisamnes was a corrupt judge who accepted a bribe and gave an unjust verdict. Once his king found out, he had Sisamnes arrested. The punishment? A slow and painful death by flaying his skin alive. The skin would then be used as a seat cover for his son to sit in judgment.
Having skin in the game means taking risks and being accountable for your judgments. Sisamnes took a risk, wasn't accountable for it, and got punished. He lost his reputation the day he lost his skin:

Reputation has moved from "what you do" to "what you say". As we graduate school, we realize that credentials aren't enough to build social capital. There needs to be skin in whatever game we choose to play. Action, judgment, and accountability are a better way to build reputation––rather than list it *ourselves* on a resume.
