A government could be good. In theory:

• one year terms for elected individuals in public offices
• no second term
• getting elected is a random draw (akin to jury duty) based on the individuals' capabilities
• authority limited in scope within city states

I'm sure there's other ideas regarding this.

In what cases is it not of a person's own doing? Barring medical conditions that would make them exempt (such as hypothyroidism or antidepressants).
