Dale Carnegie, How To Win Friends and Influence People (After all these years, still is relevant). Also, this book is not one to read and put away. After you have read the book, go back and read a chapter per month, take your time and delve into it.
Napoleon Hill, Think and Grow Rich
John Maxwell, The 21 Irrefutable Laws of Leadership, Sometimes You Win Sometimes You Learn, Good Leaders Ask Great Questions. He has a bunch. Look at his 101 series for short books to take on flights or have by your end table.
Simon Sinek,
Patrick Lencioni,
*****Dr. Robert A. Rohm (website,
https://www.personality-insights.com/leadership-disc-profile/) His personality insights on DISC is the one to use, he's even got some books on kids which will help you with your younger employees or children for that matter.
I could give a bunch more, but start with these six. Maxwell is an easy read and practical, Carnegie's book is almost 100 years old but still one of the best for everyone, Hill starts with the mind about wealth, Lencioni (5 dysfunctions of a team, overcoming the 5 dysfunctions, The Four Obsessions of An Extraordinary Executive, and some more), Robert Rohm just lays out the DISC leadership advantage so well, (you can use this from hiring to everyday life, especially your own family, yep you can understand your family better!)
Might I also suggest one more, the 5 Love Languages series by Gary Chapman. Your business(es) can't grow to it's full potential without support from your family. The 5 series is one for your marriage, your children and your teenagers. Now he has other books, and they are relevant, but why overwhelm you.
The best leadership book of all time --------- The Bible. Most on here that have read my posts know I start here, I am unapologetic that God, Jesus, and the Holy Spirit direct my life, it is His because He bought and paid for it. This is where to start with your life, your marriage and surrounding your kids (ohhhh, do they need it in this world!). All is for naught without Him. Some don't agree with me, you may not, but this is where to start. If you don't know how, reach out to me,
PM me, I can give you some pointers from a man that lead his own life for 40 something years even though I knew there was a God,
there is more.
Now if you want one for your kids, pm me, I've got one or two you won't believe. I might even find something for your marriage if you need it.
