I have come to the thought that building your marketing list is like going fishing.  If you have a positive attitude, the right equipment for the fish you are after and the most important thing other than bait is waiting, you will have a good fishing day.  But, leave one step out or try to hurry things along then what happens....Zappo!...Bad fishing day.  So what I have learned, and it costs to learn, is that if I present my best offer, to the best clients and offer them value, and wait fot the offer to settle in, after awhile, not only will I get a customer, I will also get a friend for life.  I use the fishing example because thats what I like to do, but you can use any example, as long as you understand what people want and what people are.  I say if you would buy or opt into your list yourself by reading your email or ad copy, then so will a prospective client.  What are your thoughts?....Let me know.
