That is a good way of going about it. I feel like I have a better time on the road when I say "fuck it" and focus on something else. I've actually been relatively chill since I started streaming music playlists in my car, so there's definitely credence to the idea that the more worry-free I am about my ride itself, the more worry-free my commute will be.
Mine came about at random, possibly from the strain of college and my personal life, so its not even tied to road-related trauma, which makes it a weird case. Still, I think that would be a good mentality of having on the road.
