I'm not sure why I started (and then finished!) a book on leadership, but I feel like I got a lot out of this book. Going through my notes and bookmarks (e-books are awesome!), it seems the main things I pulled out of the book were mistakes and relationships.
Mistakes are going to happen; you will make them. What matters is what you do with them, what you learn from them. One quote I highlighted was "So if you had that to do over again, what would you do differently?" I thought it was a great line for dealing with a failure - rather than the normal response of complaining, forgetting, and moving on. It seems simple, but it stood out for me. Another good example was giving her daughter a book at college and telling her to write three mistakes she made that day. "And if she was going to put them in writing, they ought to be good ones, not made-up ones. Then, she should put that journal under her pillow and fall asleep realizing 1: the world still turned, 2: tomorrow was another day, and 3: God still loved her." Excellent advice.
The other part, more in dealing with leadership was talking about relationships and getting to know the people you're working with. Story after story told about leaders who not only knew their teammates strengths and abilities, but knew them personally, what was happening with their families, what their hopes and dreams were, and what they wanted out of life... not just out of their job. It can apply to families, too. One reference she used (and I wish I knew what parenting book it was from) was that "As parents, if you and your spouse spend ten minutes a week talking about your children - what their current issues are, what you want to work with them on - you are in the top 0.2 percent of the population." I could feel pride about being in that top 0.2 percent, but the main point is to learn about your children. And your friends and coworkers. Obvious, but not always.
