ENFPs are Judicious. They will pay more attention to the planning stages before mobilizing and may divide the task into several smaller segments. They take longer to mobilize and take action. Their natural state is relaxed.
ESFPs are Strategic and ENFPs are Tactical. ESFPs consider pre-defined goals more important than the methods used to achieve them and will deviate to whatever tactics are necessary for the given goal.
