Believing that I can run a successful / viable business and do a documentary

I’ve been running a marketing consultancy for 3 years. This year, I have an ambitious goal to make 200K while also doing my documentary. As I’m thinking of taking 2 months off this summer to work on this documentary, I’m having conflicting thoughts that this will certainly negatively impact my business and that I therefore won’t reach my goal. It’s almost like I think that i can either do one or the other, but that doing both means that I can’t truly be successful at both ventures.

I’m trying to reprogram my brain by starting to tell myself that I can do both but this brings a lot of uncertainty, insecurity and anxiety.

Could you help me see other possible alternatives to empower myself to believe that it is indeed possible? Thank you.
