Cato lived a very modest lifestyle and was a very self-disciplined man. Not only did he use self-discipline for himself, but he expected it from those around him. When commanding forces, he did not give his men excess rations, but only took what was necessary for survival. When he was in Rome he often denounced the Roman Senate for its excesses and bad behavior. Cato states that "there was no need for them to change if they owed their importance to moral and virtuous conduct, since any change would have been for the worse, but if they owed it to vicious and immoral conduct, they would have to change for the better since it was enough that they were became great by relying on that type of conduct”. Cato believed that a good life could be lived without extravagance and that the extravagance he saw was wasteful and weakened men. He expelled many senators for various reasons of bad conduct, he wanted to maintain the rigor of traditions Romans who made Rome great, and wanted those in power to be severe towards them
