I just read this last week, when I was on the verge of a panic attack from over-committing myself to volunteer activities. It was an eye-opener, for sure. Now I budget my fucks (or my spoons, or my cares, etc.) to things that truly matter to me.
I also examined WHY i got myself into this mess. After some navel gazing, I realized it's because I want people to think that I'm X and Y. But I already AM those things, and I don't need to wear myself out to prove it! Especially for a cause that has a close connection to an acquaintance, but isn't dear to my heart.
The part about work also resonated with me. How they probably didn't hire you to go to pointless meetings, so just don't go. Use that time to do things that are actually in your job description!
I haven't implemented the family advice yet, except to stop worrying about certain family dynamics that aren't directed at me right now. Time enough for that around the holidays!
Overall great read, and very Mustachian
