Some money machines start small, then grow until they reach maturity.
There they may operate on a high plateau for some time. They may reach a size where it becomes difficult for them to maintain an adequate level of customer service. Then they may decline and eventually fail. For such reasons it's prudent to be always on the lookout for additional money machines. It works best to have multiple income streams.
