@Andy Black @million$$$smile You maybe interested in my bio. As a tradesman turned business owner, I've found that most hands-on manufacturing business are dying with their owners. Machine shops especially, five local shops have gone out of business in my area in the last six years. Three of which the owners passed while still operating the business.
One of many reasons @MJ DeMarco TMFL hit me so hard, these guys were slow-laners that never got to retire. Until I read that book, I didn't realize I was on the same path.
