Fail #1?

I had an idea to create a wellness collective for natural healthcare practitioners in my town.
I was super excited. I let go of coach training spot for 2018 to pursue this idea as part of my impossible 2018 (making 200K).
Many people loved the idea.
We had our first meeting the other day.
I came out of the meeting deflated – it felt overwhelming, and it felt like it would not be MY thing because everyone had opinions and wanted to take part.
I know exactly why this happened: I was NOT clear going into the meeting what I wanted out of it.
I was not clear about presenting my idea (because it’s still unfolding).
It definitely felt like a ‘failure.’
Now what?
