How did a knight's position influence his everyday life?

The knight was expected to protect his lord or king so his daily life was organized around that responsibility.  While he was expected to offer military service at least forty days a year during periods of peace, most of his days were driven by the desire to train.  On a daily basis, the knight would hone his riding and fighting skills.  He would also be expected to understand the latest military and warfare strategies.  As the Middle Ages progressed, the knight was expected to be more cultured and would have to practice dancing and other activities to demonstrate chivalry. Another responsibility, and the major source of income for a knight, was to manage his estate.  Daily inspections and other maintenance of the estate were also common for knights in the Middle Ages.
