Courage
Destroying Roman land was not only for Boudicca's benefit but for her people also. Standing up and gathering an army showed her people that she was strong enough to lead an army to battles and win. I believe this reveals Boudicca's courage to stand up for what she thought was right. Fighting with no fear or mercy, she showed men that women were not worthless.
Pride
After she had fallen from her throne, she stood back up knowing that she was going to get revenge because her pride was something no to be toyed with or be thrown away so easily. Boudicca had a soul which people would be feared or admired greatly. But mostly it would depend how you look at her. In my eyes, Boudicca was a strong woman to be admired. She, herself, showed a strong amount of courage, giving herself hope.
