Below are links to some lists of great personal development and other insightful books.
A list of the proven books that are regular names for anyone that has ever looked into it. The list will be generally the same no matter where you look… for good reason! Generally ones that everyone has or should read at some time.
Other Classic or Under-Appreciated Books
The ones that might be considered classics depending on who is putting the list together. (Everyone should read these next). Start here if you are looking for some real ‘new’ insight or different thoughts that are not the same old things that everyone already knows.
Lesser Known Books (that are awesome!)
Those that have not really (yet!) reached the level of popularity and awareness that they deserve.
Depending on who you are or where you are at in your life, these may really speak to you. They may not all be traditional ‘personal development’ books but these are all a great place to start (or refer back to) if these topics relate to you
