Grit: The Power of Passion and Perseverance Grit: The Power of Passion and Perseverance ($10, originally $18) is the book I'm currently reading, and I love it so much. Angela Duckworth was actually a professor of mine in college, and her research is meaningful for anyone trying to live a more fulfiling life. Everyone should read this book.
