I started reading the book :
This book is very interesting and philosophical and have a vast knowledge on every aspect of life. I think most of the question will be answered by the book. I suggest a must read.
The first lesson from the book is on the “Control and Choice“. Control and choice meaning, we should only think about the things that are in our control and stop worrying about the things that are not in our control, so we have only our choices in our control and not the out come, so only think about the choice not the result.
“The chief task in life is simply this: to identify and separate matters so that I can say clearly tomyself which are externals not under my control, and which have to do with the choices Iactually control. Where then do I look for good and evil? Not to uncontrollable externals, butwithin myself to the choices that are my own . . .”—EPICTETUS, DISCOURSES,
From the book, i have taken the below phrase:
The single most important practice in Stoic philosophy is differentiating between what we can change and what we can’t. What we have influence over and what we do not. A flight is delayed because of weather—no amount of yelling at an airline representative will end a storm. No amount of wishing will make you taller or shorter or born in a different country. No matter how hard you try, you can’t make someone like you. And on top of that, time spent hurling yourself at these immovable objects is time not spent on the things we can change.
As in Bhagavad Gita Lord Shree Krishna said “karmanye vadhikaraste ma phaleshu kadachana“
