Stoicism

Stoicism is an ancient Greek and Roman philosophy about how to live a good life.

To summarize, one of its main ideas is the dichotomy of control. This is just a fancy way to say some things are up to us and some things are not. In other words, some things are in our control, and some things are not.

Its best-known book is the Meditations by Marcus Aurelius, and it's still one of my top book recommendations.

Stoicism was the philosophy that got me into a life of philosophy.

It eventually led to me becoming a Catholic, and that has been my worldview and my philosophy. I wrote about that in Stoic to Catholic.
