I do believe people can utilize other functions even though they might have a natural preference for specific ones. I tend to have a preference for Ne, Te, Fi, and Si, but there have been moments in which I've found that utilizing Ti+Fe and even Ni+Se can be helpful. Those are sides of my mind that I tap into... again, they are not natural, but they do give me a new and interesting take on things. Does anybody else (who knows what they're talking about) do this? When I get into my Cogntive Functions world or get involved with something that takes focus, I can flip a switch so to speak. This is an interesting thing to try to explain, but I push aside my natural tendencies, and adopt other functions. Shit, I sound whacked, but can I get a witness?
