Below are books that I've found very valuable.

The book Mindset by Carol Dweck is outstanding.  It has really made an impact on how I think lately.  For so long I had a fixed mindset and did not even realize it.  I read this and instantly saw my shortcomings and faults.  If I had to recommend one book for anyone looking to change their ways, this would be it.  Besides the Bible of course. Click on the text above to find it.

Can’t Hurt Me by David Goggins.  I’ve listened to the Audible version and it is outstanding and a little bit different than the written version as David and the author have discussions between the chapters.  This is a story of overcoming great adversity and insurmountable odds.
If reading this does not inspire you, nothing will.  Beware of the language if you are a bit sensitive but the message far outweighs this awesome, inspiring true life story of David’s life, more commonly know as just Goggins.  A MUST read in my opinion.
