Alchemist by Paulo Coelho is an amazing book. It has a huge impact on me.
Explanation:
The book is talking about a dream and later it comes true. The process and the time took for it come true is described in the book.
There are several quotes in the book which will take your mind. If you read that, those quotes will hit your mind every day.
The changes that the book made in me is that when you have a dream and if you strongly believe in the dream then the whole world will make/ help you to achieve that. Hence, believe in your dreams and work for it.
