It is about being happy and putting an end to negative thoughts.
Example: you can prepare all you want for a job interview or a date, dress appropriately, rehearse all you need, this is all something you control. But ultimately you have no control over their final decision, so you shouldn't let it negatively affect you and be mad/sad/puzzled. Reach for rationality, understand why you failed and improve on this for the next time
Radical Candor: Be a Kick-Ass Boss Without Losing Your Humanity, by Kim Scott
Another book that sounds similar is The Subtle Art of Not Giving a F*ck (https://www.amazon.com/dp/B019MMUA8S). I don't know exactly how it compares to The Gifts of Imperfection as I haven't read the latter. The former talks about how you aren't as special as you have been told and how that's not only perfectly okay, but really freeing.
You learn to forgive yourself once you get over yourself. Stop acting like you can be some perfect being and have a happy life if you just: earn lots of money, get that fancy car, get married, etc. They won't make you happy in and of themselves.
The same goes for your career, too. Some things are going to suck and that's okay. You can't fix everything and "you only have so many fucks to give". You have to constantly decide what to give a fuck about and stop giving a fuck about things you don't. That last part sounds redundant, but can be hard to actually do.
See Font Awesome 5. When they announced the KickStarter on HN, a minority criticized the existing library (like how the lib is shitty) or their future plans (like how having a pro version is wrong). But at the end, they raised almost $1 million. That shows how the biggest part of the community is really thankful.
If FA5 can raise $1M, I can't even imagine how much could raise Babel, Webpack or Homebrew. You made our lives so much easier.
Also, can't recommend enough this book:
The Subtle Art of Not Giving a F*ck: A Counterintuitive Approach to Living a Good Life - https://www.amazon.com/Subtle-Art-Not-Giving-Counterintuitiv...
1) Reading HN all the time creates a false sense that things are moving much faster than they really are.
2) I'd suggesting reading "The Subtle Art of Not Giving a F*ck" and it'll remind you your time is finite
