Which House To Use For a Vision Board

I made a vision board with 4 different sections - home, travel, love, and self. I cast a chart asking if the vision board will work in bringing in the things I want for this year.

First, what house would one technically use? I looked it up and a site said the 12th is the final stages of the project, so... 12th? Or should I use the house designated for each subject instead? (4th, 9th, 7th, and 1st?)

I suppose 11th would actually be better... astrotheme.com lists it as representing the native's projects, and not only that but it's the house of wishes.

9th. (at least 10 characters)

Thank you!
