depends what kind of self growth you want but some of my favorites I've read in the last couple years are 'swing' by Dan Hawkins, 'how to win friends and influence people' by Dale Carnegie, 'how I raised myself from failure to success in selling' by Frank Betger, 'the magic of thinking big' by David Schwartz, "start with why' by Simon sinek, "eat that frog" by Brian Tracy, 'becoming a person of influence' by John Maxwell, 'atittude is everything' by Jeff Keller and 'Resolved' by Orrin Woodward
