The Hávamál

translated from the original by Björn Jónasson ISBN 9979-9070-0-2. As usual I'm going to quote from a few pages:
The ethics of the Hávamál are above all rooted in the belief in the value of the individual.
Attending a feast: No man should call himself clever but manage his mind. A sage visitor is a silent guest. The cautious evades evil. Never a friend more faithful, nor greater wealth, than wisdom.
Happiness: He is unhappy and ill-tempered who meets all with mockery. What he doesn't know, but needs to, are his own familiar faults.
Financial sense: Become not a beggar to the money you make. What's saved for a friend a foe may take. Good plans often go awry.
Moderation and prosperity: Moderately wise a man should be not too crafty or clever. The best of lives is led by those who know the measure of many things.
Shyness: A log's flame leaps to another fire kindles fire. A man listens thus he learns. The shy stays shallow.
Foresight: A man should know how many logs stubs and strips of bark to collect in summer to keep in stock wood for his winter fires.
The use of power: A prudent man wields power in modest measure. With brave men he finds that none is foremost or excels in all things.
Everyone has his use: The lame rides a horse the maimed drives the herd the deaf is brave in battle. A man is better blind than buried. A dead man is deft at nothing.
