By John C. Maxwell
I'm a huge John Maxwell fan. Back in the day, I used to listen to his Injoy Leadership tapes while delivering pizzas. To me, it was the best job; I got paid to listen to Maxwell on Leadership and occasionally free pizza. I actually told him that story when I met him back in the Winter of 2015. He laughed and then I seriously thanked him for all his books and teaching.
This book, in particular, is potent for personal growth. I like to think that his 12 daily practices are like the fundamentals. You've got to learn them and keep practicing them. Don't miss this book.
