This is some of the stuff that I copied from the site I was looking at. There are things that show up in both, or at least things that are very similar in both. If you want me to comment or explain why I pulled some of these things I can tell you where I was coming from.
Their primary goal is to find out their meaning in life. They rely heavily on their intuitions to guide them, and use their discoveries to constantly search for value in life. They are on a continuous mission to find the truth and meaning underlying things.
They focus on the way that the conflict makes them feel,

When it comes to the mundane details of life maintenance, INFPs are typically completely unaware of such things.
INFPs have very high standards and are perfectionists. Consequently, they are usually hard on themselves, and don't give themselves enough credit.
ENFPs have an unusually broad range of skills and talents. They are good at most things which interest them. Project-oriented, they may go through several different careers during their lifetime
An ENFP needs to focus on following through with their projects.
Others may fall into the habit of dropping a project when they become excited about a new possibility, and thus they never achieve the great accomplishments which they are capable of achieving.
They see meaning in everything, and are on a continuous quest to adapt their lives and values to achieve inner peace.
Because ENFPs live in the world of exciting possibilities, the details of everyday life are seen as trivial drudgery. They place no importance on detailed, maintenance-type tasks, and will frequently remain oblivous to these types of concerns. When they do have to perform these tasks, they do not enjoy themselves. This is a challenging area of life for most ENFPs, and can be frustrating for ENFP's family members.
They may become unhappy when they are confined to strict schedules or mundane tasks
