Have you ever taken a personality test?
Phil teaches a Vocations class to his seniors, and they cover personality types as a way of helping one determine where their calling may be. If someone is a loud, funny, center-of-attention type, then maybe the monastic life wouldn't be well-suited for them. I guess the point is that if you know your strengths and weaknesses, then you can use them to help find your calling. Of course, God can laugh and make even the most party-going extroverts become holy and serene Saints (hello, St. Augustine!) but it doesn't hurt to know thyself.
We both took the test here and found out that I am an INFJ and he is a ESTP.
You can read more about the types and what they mean on the link above. Basically I am an introverted, intuitive, feeling and judging person while Phil is an extroverted, sensing, thinking and perceiving person.
So tell me....what personality type are you?
