Pride is one of Odysseus' greatest weaknesses. It is what costs him so much loss of time on his way home. A good example of this is when he taunts the cyclops and is then cursed by Poseiden. His other weakness is his curiosity. While we may not consider this a weakness, for Odysseus it is. If he had not spent so much time exploring the Cyclops' cave he would not have lost a great deal of his crew. Lastly, Odysseus was easily given to temptation. This is evidence by his looong stay on the island of the Sirens.
