Whilst this book is written for teenagers, it equally applies to adults. It is written in plain english, is easy to understand and full of pictures/stories. Most of all its FUN to read. It is like reading a textbook without evening knowing it!! It covers habits that we all need to develop - whatever age we are -taking responsibility for our lives, defining what you want to do in your life, prioritising, adopt a win-win attitude, listening to people, working togehter and taking care of yourselves. I loved it - would recommend it to teenagers, their parents, trainers or just anyone looking for self development.
