Being overly concerned about where to start often precludes one from starting. Think Nike, "Just do it!" Seldom can one ever get it right the first time, just think "Trial and learning."

Escape behavior often results in more stress than one escapes from.

A Growth and Underinvestment structure is simply an elaborated Limits to Growth structure where the growth inhibitor is part of another Balancing Loop with an external standard and some delay. The real nasty thing about this structure is that the two Balancing Loops form a single Reinforcing Loop which inhibits growth.

Two goal seeking structures attempting to resolve and based on the delay one may tend to settle for less. See also Archetypes.

A simple Susceptible - Infected - Recovered disease as a stock and flow model.

It's relatively well understood that you can't be all things to all people. Somewhere one has to make choices. An Attractiveness Principle Systems Archetype is essentially a Limits to Growth Systems Archetype with multiple limits, all of which can not be addressed equally.

Sector Relationships

The Reinforcing Loop Systems Archetype is one of the two most basic Systems Archetypes. The Balancing Loop being the other one.

Investigations into the relationships responsible for the success and failure of nations. This investigation was prompted after reading numerous references on the subject and perceiving that *Why Nations Fail: The Origins of Power, Prosperity, and Poverty* by Acemoglu and Robinson seem to make a great deal of sense.
