Luxuries provide a false sense of security. If your life requires regular infusions of luxury because you feel fundamentally unsafe, if you cannot feel relaxed and comfortable wherever you are and however your circumstances change, then you are a slave to your own fears. (…)
One way in which security and freedom are very close is that freedom from need creates security. The less you need to live happily, the more secure you are. The fewer sacrifices you need to make. The less can be taken away from you. The harder it is for fate to plunge you into misery.
