Give me a list of some of the core beliefs in Stoicism

Response:
1. It is important to live according to Nature for a smooth flowing life.
2. Happiness is found in Virtue, our values and choices.
3. We can only control our internal world, i.e. thoughts, opinions, and decisions, but have no control over external events.
4. We are responsible for our own life and hence should not complain or blame anyone else.
5. For our personal development, we need to act in society and try to live in harmony and cooperation with others.
6. Progress is driven by having a pragmatic attitude, not via perfection.
