I was wondering if there is a list of steps I can take to screen my variables for assumption violations prior to using them in my GWR. I have watched this video tutorial :

However, I am still a little bit confused. I understand from logic and background information the types of explanatory variables I expect to explain my dependent variable (these account for about 4-7 from the >20 exp. variables I have. What I don't understand is how to convince myself I should not use certain ones.
The video tutorial suggesting using Scatterplots and OLS (ex VIF value, non-stationarity etc) prior to using GWR. It was my understanding from readings on this forum that I should not use OLS to screen variables for GWR. Thus, I am a little confused.
