You make claims like "I am not even a tiny drop in the giant ocean of talent" and "I will never be as good," but that's just pure mental melodrama. The actual, real-world observation you've made is this: "There are people here who have done things that I haven't."

That's all. It's just about doing things. In many of these cases, you've chosen not to do these things. So you only really know three languages? Has somebody threatened to shoot you if you learn Ruby?

Most of your supposed "inferiority" is just the fact that they've chosen to do some work and you haven't.
