In economics, I learned about something called a "trade-off". Basically, if you spend time learning something, you are spending that time not learning something else. I remember meeting someone who was fantastic at chess. He destroyed me. Repeatedly. My mental model of him was essentially "me but good at chess". It didn't occur to me until much later that he didn't know how to program a computer, couldn't run a mile without stopping and didn't know how to cook Chinese food. I think if you stop seeing people as "you but can do X", these feelings will go away. Alternatively, read up on the concept of "comparative advantage" and realize there is a mathematically proven reason not to try to be an expert at everything.
