Zig Ziglar is amazing I would recommend any of his books, also his audiobooks are amazing, as they are like attending one of his shows, and the manner in which he speaks is very entertaining to listen to. The information contained therein so vital for what we do here. Lately, @jongolson has me hooked on Brian Tracy 😀

Thanks
Can you help me with a link to start

You can find any of Zig Ziglar and Brian Tracy's books on Audible, Amazon, eBay, and many other places on the internet. For example https://www.ebay.com/itm/143516689508?epid=135575&hash=item216a42e464:g:B1UAAOSwnPBf~w8f
