Is it getting traffic?
Is it getting the squeeze pages done?
Is it knowing what copy to write on your squeeze pages?
Is it knowing what to offer to get people on your list?
Is it knowing what to do once you build your list?
Is it knowing how to write to your list?
Is it finding offers to promote to your list?
This could be an issue you are having right now or perhaps you could share what you have struggled with in the past and overcome.
Really interested to hear your thoughts.
