If it makes you feel any better, I am also not very good at anything I do regularly, and I don't even have any tips for coping with it.
My latest confirmation of this is that after practicing FPS aim almost every day since 2019, I just got a copy of KovaaK, where all my scores are legit 1-10%ile on every challenge. Like sure the top scores might be a self-selecting group of showoffs, but damn.
Still, you can specialize in a kind of cuisine you like and be the local/family "expert". Sometimes, expertise is just about being the person who bothers and is available, not absolute terms.
