Sure, life is challenging, frustrating and difficult, but at the same time, life is short and valuable. Basically, life is meant to be enjoyed and not to be taken too serious.
We've all made different mistakes in the past. We all have regrets, and we wished we can go back in time and change some things. It would have been nice if we were giving an instructional manual on how to go through life in order to avoid silly mistakes, but unfortunately, none was given to us. We all have to learn from our mistakes.
Among other goals, one important goal of this book is to show you how to live life on your terms and create the kind of future/life you desire so you can have fewer regrets and more happiness.
