One of the stoic principles

The ideas behind the philosophy of stoicism are very interesting as they have a lot of overlaps with the practices of many Eastern systems such as Buddhism.

Stoicism is essentially a system of personal ethics.

One of it’s interesting teachings consists in not worrying about other things or people as these are not under our control. Instead, it is suggested that, since the only entity which can be changed is oneself, one should focus on improving oneself and making oneself more stoic and resilient.
