Many of us, including myself are asking this question every single day, and most of us can’t find the answers even by our last day on Earth. Over the years that I have lived, I found that people have different purposes in life, and you have to go and find it yourself. No one can tell you or teach you.
Currently I am confused and still finding, but recently I read something which have given me some ideas. Perhaps you can go read and hope that this will help you to find one day. Let me paste some of the texts in the books, do read them. Perhaps those who read this book before can guess the title of this book.
From the above, below is what I have learned. Hope this is useful to you to find your purpose in life too....
