I read this book in English and learned more about understanding life than I have in my whole life. I thought it will make a great gift for friends and family members but most of my relatives speak Spanish. Luckily, the book is also available in Spanish. I bought one and will be buying more soon. It is a great book, with a great teaching. I recommended it to anyone who wants to grow as a person and make their lives better. Mr. Ruiz shows a great wisdom in all he teaches in his book and is very enriching to read words of such wisdom that will easily change your life forever.
