August Purpose

Hi! So after much deliberation and rewrites, I determined my purpose to be, I want to become the editor/publisher of the seaside newspaper I write for when the editor retires. The thing is, I can want this all I want, but it all comes down to when and if she retires, something totally out of my control, making me question if this is an appropriate purpose for me. Am I better to just have the purpose, to be a successful writer and spend the month getting specific about how I can achieve that?
Last August was my first month in scholars and I was too afraid to make being a successful writer my purpose. I indulged in fear and pushed aside my forever dream of being a full time writer with my own business. I’m still scared but I’m also excited and looking forward to brainstorming ideas.
Thank you for any insights here:)
