Reddit reviews Introvert Power: Why Your Inner Life Is Your Hidden Strength

That was a pretty good book for me too.
Happiness Advantage by Shawn Achor was awesome for me since a lot of times I get depressed or feel like I am not accomplishing enough in my life, and this was great to reorient me on what matters and what I have control over.
Introvert Power: Why Your Inner Life Is Your Hidden Strength by Laurie Helgoe was a really awesome read for me too.

Edit: I also like Quiet Revolution which has a decent amount of interesting articles and such. It was started by Susan Cain.

I've only recently appreciated and accepted that I'm introverted. At first, it seemed to make my introversion even more pronounced, making social interaction even more painful, perhaps because I wasn't fighting it so hard anymore.

I don't know if this book is popular here or not, but I found it encouraging: "Introvert Power" talks about the strengths of introverts. The author rejects the idea that being an introvert is a bad thing. It helped me appreciate the beauty of introversion, and now I'm trying to learn how to revel in it.

Above all, remember there are a ton of us out there. Find others like you, and a lot of these problems will ease. And, Facebook is quintessentially extroverted. It just makes me miserable (and you too, apparently!).

Although my husband and I are generally on the same page with parenting, we also have our differences. But we both know that it is important to be on the same page, parenting wise. I would also expect that your husband would actually like to have things more harmonious. Both between him and his daughters and between you and him. A babysitter is a short term solution. You need a long term solution.

In our house, we are both readers. And have found some really wonderful resources that reflect the approach to parenting that we both aspire to. I subscribe (both e-newsletters and on Facebook) to Aha Parenting and Janet Lansbury. I will share 1 article with him at a time and then we'll talk about the article, often when doing dishes after the kids have gone to bed. There are a few books out there that line up well with these philosophies. We have a shared kindle account so we can both read the same book on our own devices and highlight, etc...

The other thing is the understanding of being introverted. Both for him and for you. It can be tough to be introverted and a parent. Especially if you have an extroverted kid. But there are ways to embrace this and be proactive with your needs before lashing out at the ones you love. Some books: Quiet: The Power of Introverts in a World That Can't Stop Talking, The Introvert's Way: Living a Quiet Life in a Noisy World and Introvert Power: Why Your Inner Life Is Your Hidden Strength.

It really seems like you both could use some understanding of the situation and try to get to a better place with it. It's hard!

I did a search on Amazon for books about Introverts. These two seem to be the popular ones (although neither one is as popular as Quiet):

https://www.amazon.com/Introvert-Advantage-People-Thrive-Extrovert/dp/0761123695

https://www.amazon.com/Introvert-Power-Inner-Hidden-Strength/dp/1402280882

Both of these are written by people with degrees (presumably in psychology), and they both reference "energy" in their summaries. Introvert Advantage even predates Quiet by a decade. It was published in 2002, so it might have been on the forefront of shifting the popular definition from "asocial" to "loses energy". I suspect that while they probably reference "energy", it's probably still more nuanced than today's popular definition gives it credit for. I think these books are also worth putting on my reading list. (Or at least, Introvert Advantage is. It shows up in almost every "customers also bought" section for every other book about Introverts.)

I also found this on Wikipedia https://en.wikipedia.org/wiki/Energy_(psychological) (Although admittedly, it's Wikipedia, so it's a secondary source at best.) But it suggests that psychology has a separate concept of "energy" that's not physical energy. I can sort of see this. I'm in a much better mood when I get a lot of alone time, and I'm in a really bad mood when I have to be in a social situation for extended periods of time. But honestly, whether I'm in a bad mood because I don't enjoy socialization, or whether I don't enjoy socialization because it puts me in a bad mood isn't really an interesting distinction.
