Hello nairalanders.. book lovers especially...
Please recommend a book for me that can harden my heart, make me fearless,.. brutal and more heartless when I read and practice what is in the book.

My reason for wanting to read this book is as follows;

People taking advantage of others and going scot free without being harmed..

I am a soft hearted person and as such when k do things for free out of freewill, some people around me gossip and talk why will I do this for free or less and many more
