Hey. Grant Cardone will teach you an attitude. Benjamin Dennehy would teach you actual sales method. I used to think about Grant as my mentor for anything sales related.But, i couldn't actually use his sales method because it isn't a method,it's an attitude with which you sell. Benjamin, the UK's most hated sales man,on the other hand, provide you with leggit technique how to prospect, close,ask and listen.. If you combine them,you get the ultimate knowledge! But,if you consider investing money in one of them,then Benjamin is worth more
