Why I'm writing this book? & How this book will help you? From my college days I started developing my interest in various subjects like Investment, Astrology, Spirituality, Stock Market and so on. To gain in-depth knowledge I started my research about various subjects and it helped me a lot at my initial stage. After that when I got my first job then I got the opportunity to invest in myself so that I can be a better version of myself. From that time, I started buying different books to enhance my knowledge. My initial target was to buy those bestselling or highly famous books so that I can learn something new. It took me long time to complete a good number of international bestselling books. Now when I look back, I can realize that how much time I spent to learn about various things in detail but I don't regret about that, rather that time was one of the best times of my life. Now the question is, does everyone have that much time to invest in themselves so that they can develop at least basic knowledge about a few subjects or topics which are very relevant to our life? Though we have time, but in majority of the cases we don't want to invest our time in reading books! In this book, I've tried to give everyone fundamental knowledge about various subjects in a summarized way. Upon reading this book, you will get to know about various things.
