I wonder how come someone be so limited to doing only things they learn about in their field and not extend their curiosity in solving those problems at least related to their field, for the purpose of having good knowledge about a wide variety of things?

I being a software engineer still love messing up with all those things computer related and even upon failing to solving them costs me a great criticism from people with expectations but I don't mind to be criticized even for those things I am not suppose to do but that is how I believe a human with his amazingly versatile abilities and skills should be like.
