Be careful whom you associate with. It is human to imitate the habits of those with whom we interact. We inadvertently adopt their interests, their opinions, their values, and their habit of interpreting events.

– Epictetus

It is only luxury and avarice that make poverty grievous to us; for it is a very small matter that does our business, and when we have provided against cold, hunger, and thirst, all the rest is but vanity and excess.
-Seneca the Younger
