Some things are up to you
Echoes, per a summary

“There are things which are within our power, and there are things which are beyond our power. Within our power are opinion, aim, desire, aversion, and, in one word, whatever affairs are our own. Beyond our power are body, property, reputation, office, and, in one word, whatever are not properly our own affairs.”
Epictetus, Enchiridion. Earliest we can find, about 1,860 years earlier.
- 1989
Wikipedia’s account of the book: He goes on to introduce the concepts of the Circle of Influence and the Circle of Concern, advising individuals to focus their responses on the center of their own influence.
Secondhand, from Wikipedia. Stephen R. Covey, The 7 Habits of Highly Effective People (1989).
