I like literature. Poetry opens my mind. Lyrics are a rhythm for me to move along to during the day. I'm a lyricist for Gudda Boi Classics.
Throughout history there have been rivers. Rivers have been used for passageways. A passageway is a route used to attain a need or a want. Rivers near resources. Resources such as iron. Iron has been used by blacksmiths to make weapons and tools. Resources such as gold. Gold has been used for jewelry and decorations especially in trade.
Whoever is nearest to the resource will not have to exude as much energy during there search for what is value in trade.
A river is another valuable resource because they carry food such as fish and water to drink. The owner nearest to the resources may ery want to be prepared for a rival and should prepare a trading regiment to avoid a war of conflict.
