The Money is Not in The Banana Stand
The money is in the list. This is an old phrase in sales and marketing. What does the money is in the list mean? The money in the list means that you should build a list of leads and customers, go to this list to sell your products and services. These people are likely to buy from you if you build the list correctly.
The list has evolved a lot. Before computers, the list was a mailing list and companies would send you magazines or catalogs. Then a telephone list and the Rolodex became your list. Later came e-mail. And social then SMS.
The best list is the email list. But your followers on Twitter constitute a type of list, and your fans on Instagram are yet another type of list. Don't neglect them.
Spend time nurturing your lists. Especially the ones where you can connect with the members directly.
