Still get nervous about riding fast on the flat of my board

I’ve been riding for a pretty long time and I still get some anxiety about keeping up speed on long catwalks and flatter areas. I haven’t eaten serious shit ***knock on wood*** on one of these in a pretty long time but I feel like it is probably because I’m being overly cautious and wearing out my legs in the process. I have no issues with steep runs or anything like that but a long flat catwalk will send my anxiety through the roof. If I try to stay on an edge the entire time, I lose the speed needed to get through it. If I ride on the flat of my board for too long, I risk catching an edge and seriously eating shit. I see some people cruising by on these flat areas pretty fast. What am I missing?
