    A Book I Wish I Had Back Then
    Format: Paperback
    This is EXACTLY the sort of book I wish I had available to me when I was ready to leave home. I was filled with all sorts of braggadocio and I knew everything I needed to get out the door..............and then was introduced to the 'school of hard knocks' From discovering how to budget and manage your money, to learning how to cook and eat healthy food, to figuring out how to start a career, this book has something to teach even the most well rounded youngster. These aren't in-depth discussions about every aspect of how to live your life, but these ARE a great starting point and with the knowledge provided here, and a little bit of common sense, you can survive early adulthood and move towards a more fulfilling life. Life is a series of learned events, usually set it motion through observing the people we respect, but not everyone can be everywhere at once and this book can and does fill in a bit of this and a bit of that, often inspiring a conversation that will provide more opportunities to share life lessons and avoid some of the bumps and bruises life has to offer. As a grandparent watching his oldest grandsons get ready to leave the nest, I found this book to be a helpful way to share my experiences in a way that goes well beyond "because I said so" and reaches into the 'how' and the 'why', even explaining the reasoning, all without seeming to meddle in their affairs. Unlike childhood where you can stomp your feet, declare 'that's not fair' and receive an immediate 'do-over', real life doesn't offer that and it's best to be prepared for what life is going to bring you. This book does that.
