Wisdom for Today from the Vikings

Let a man never stir on his road a step without his weapons of war; for unsure is the knowing when need shall arise of a spear on the way without.

................

All the doorways, before one enters, should be looked around, should be spied out; it can’t be known for certain where enemies are sitting in the hall ahead.
