You are perhaps thinking something like I am putting all this work into creating a membership - do people even want this? 
I’m sat at this computer for hours creating content for them is it worth it? 
Deep down the secret isn't actually you are scared of the hard work its what if you fail? What if nobody buys? Correct? 
I share my experience The membership mastery story 
Then you get your first  sign up 
The community starts to build 
You get testimonials 
Realise you are really enjoying serving them…. 
They share 
The secret : Every week you get better
