Before and After Models


I have been trying to figure out my C for before and after models when I am working on starting a model with a result. I get tripped up by it. For instance my current R is my current income, but I want my income to be different. My current C is that I work 40 hours a week at my current place of employment which gives me my R(income).

I want my R to be a different income from working my business full time instead. Does the C change when you are doing a before and after model? Where I’m at now is working a job and where I want to be is working my business.  Can the income model and job situation model be two different models then?
