We are frustrated by politics, and are proposing to limit terms automatically, by law.
Couple of problems to consider.
1) It takes 10,000 hours to get good at any skill. We would be firing people who have learned their business;
2) Inexperienced elected officials would shift power to their unaccountable, unknown, experienced staffs, mostly rent seeking, big government lawyers;
3) incumbents are nearly impossible to get rid of, so enact direct voting on issues, in all US jurisdictions, as California Initiatives do. This is direct democracy. These drive politicians crazy.
