In my opinion, you do not give up on anything or anyone, I treat my CSAs exactly like my PSAs, the PSAs are also CSAs someone! They are all part of my downline. For every hundred contacts that I do, I get less than 5% return, it is obvious that we receive feedbak is good, but for me the important thing is to be heard and pass my message. Later or sooner will gain their trust and be more active to their contacts than their PSAs.
