What are some of your favourite self help books?

I like the giving way to happiness and the rabbit effect.

The first book is about the emotional and psychological benefits of being nice to others.

The second book is about the medical and biological benefits of being nice to others.

One is written by a billionaire sponsored wealth management C. E. O.,

The other is written by a top mental health doctor who has worked in various research capacities at top medical organizations.
