Stoicism says we should stake our well-being on what we can control and let go of any attachment to what we cannot.
There are many forms this philosophy takes all concluding that we should avoid worrying about or being anxious about what we can’t control. Examples include: events, opinions or behavior of others, or whatever is outside ourselves.
This is a lot easier to say than to do, and it ignores the fact that part of our lives is under the control of others such as the government, our employers, and our obligations to friends and family.
Maybe we should consider not worrying about things we can’t control and spending our efforts on our own judgments and actions, remaining aware that we become attached to things we can’t control and this can lead to misery.
I think it all boils down to awareness.
