Why Musashi and Nietzsche hated resentfulness

Musashi and Nietzsche on why it isn’t good to be resentful of others. Ressentiment is the hatred one harbors towards another who they envy do to having or being able to do things the resentful individual cannot. While it is easy to complain about our lack of success and blame it on others, even if it’s true, it won’t change anything. Only we can change our lives for the better. It is better to be a Warrior rather than a Victim.
