Just as an anecdote, I do remember raging as a kid (5-6) when I was failing to build a Lego properly, and then being extremely quiet (concentrated) while playing Counter-Strike for (too many) hours as a teenager. But I get your point :) I think it takes time and practice for people to acquire emotional stability. It can also be domain-specific. As in, you can have a lot of patience solving technical problems, but not a lot of patience dealing with people (or vice versa). Some of it perhaps is transferable, but I'm not sure to what extent.
