are workers. They can throw themselves immediately into a job that attracts them and go all the way to the end with it. They will get things done at often at the expense of other necessary tasks and their own private lives. They are rational, and need practical objectives to be working on. Without defined goals they will make up a reality and a reason to be getting on with their work. They are always capable, but are concerned with impressing themselves on the spaces around them regardless of who else is there.
