{{Quote|A '''stock''' is the foundation of any system. Stocks are the elements in the system that you can see, feel, count, or measure at any given time. A system stock is just what it sounds like: a store, a quantity, an accumulation of material or information that has built up over time. It may be the water in a bathtub, a population, the books in a bookstore, the wood in a tree, the money in the bank, your own self-confidence. A stock does not have to be physical. Your reserve of goodwill for others or your supply of hope that the world can be better are both stocks.
