“When we desire more than we need, we make ourselves vulnerable. When we overextend ourselves, when we chase, we are not self-sufficient. This is why Cato declined expensive gifts, why he did his political work for no pay, why he traveled with few servants and kept things simple. A Spartan king was once asked what the Spartans got from their ‘spartan’ habits. ‘Freedom is what we reap from this way of life,’ he told him.”
