And when it came right down to it, the answer is - build relationships.
Sounds simple, right? Well, it is! People just don't think about it this way. It is my opinion that we think about what we can gain instead of what we can bring. I'll give you an example. When you decide you are going to add people to your enewsletter list without asking them if they want to be added, you are doing it because you want to be in front of them; you want to build your list. That's all about you.
When you ask someone if they'd like to be added to the list, you are thinking about them. You've listened to them and you've determined that they might gain something from your words. You are now bringing value to someone else - which in turn will bring value to you!
Think about your market. Think about what they need or want. Think about how they want to be treated. Think about how you can help them so they want to be around you. You'll find that you gain more followers and enews subscribers this way than the other.
