Guy Spier is one of the kindest, humble and most genuine individuals you will ever meet. I've talked to him several times, been to conferences with him and had dinner with him in Chicago. He is always willing to help out, give you a referral, etc - he walks his talk. His book is completely genuine.
You can't ask for a better role model in how to live your life.
It's very clear to me that Oct 7th - and the reaction from much of the world horrified Guy - as it did many of us. He's Jewish with friends of all faiths - and yes, I did see some of his posts expressing his outrage at the behavior of anti-semites. Every man has his limits - and obviously many crossed the line with Guy. That is 100% understandable.
I pray that such a good man gets a miracle cure and remains in good health with his family.
If you never met Guy in person - you missed meeting someone very special. I consider myself very lucky in that regard.
