Should you build an audience BEFORE you create your course?
OR.. should you create your course and THEN build an audience?
You should always be doing both at the same time. You NEVER ever stop marketing. You never stop building an audience - however, you certainly should NEVER wait around a delay making money until you have a certain number of 'followers'. That is a futile waste of precious time. Start audience building NOW and also start selling your products right NOW.
