Thanks Joe it’s refreshing how clearly you explain things. I think you would put these kinds of videos more often

Your welcome and thank you for the comment. I’m working on a video now on the 3 and 4 times rule. I’m trying to get a video out every 2 weeks,this one I’m working on has taken alittle longer. Should be done soon !
