For me these are the concepts I've internalized that have helped me not get butthurt about situations I don't like (still happens from time to time. But we are only human )
1). Man's Search For Meaning by Victor Frankl
2). Alfred Adler's Separation of Tasks:
One should ask, “Whose task is this?” Then do the separation of tasks. Calmly delineate up to what point one’s own tasks go, and from what point they become another person’s tasks. And do not intervene in other people’s tasks, or allow even a single person to intervene in one’s own tasks. Not wanting to be disliked is your task, but whether or not so-and-so dislikes you is the other person’s task.
3). A guide to the Good Life: The Ancient Art of Stoic Joy by William Irvine
There are two kinds of desires: things that are under our control (e.g. eating less) and things are that are not under our control (e.g. less rain in Seattle).
If we want things that are not up to us, we will be upset when things don't work out and we don't get what we want. We also feel more anxious during the pursuit of something we can't control because we know that we can do everything possible and still return empty-handed. This anxiety manifests itself regardless of whether we end up getting what we want.
Thumbs up for this one. That book is so packed with wisdom it's fucking ridiculous. Extremely relevant when you are dealing with hardship. If things are good already and you are looking to aim even higher, then maybe not as useful, though.
A few quotes In addition to Velasco's which, imho, neatly summarises a big chunk of stoic philosophy:
“Between stimulus and response there is a space. In that space is our power to choose our response. In our response lies our growth and our freedom. ”
