Reconciling the path for business goal for this year

Hi Brooke and coaches, I am working carefully through the Entrepreneur course in preparation for my Impossible Goal of 100K in earnings in my own business in 2019 (currently $0). In the 10 Year Plan video Brooke encourages watchers not to set the revenue goal too lofty in that first year. Now I’m doubting my goal! I get that I’m doing the confusion thing . . . again . . . LOL. Further light to be shed on this idea? I still firmly believe in the impossibility of my goal, so that’s good? I guess? LOL
