As an aside, I'm not sure if I'm fit for life in a Benedictine monastery. I'm physically weak and enjoy having personal possessions.
I am not sure there is any human being alive that doesn't enjoy having personal possessions. The question is not whether you enjoy personal possessions, the question is whether you can give them up for a greater gain.
Rather than entangle yourself with the Novus Ordo where most Catholics lose the faith, I strongly encourage you to talk (yes, just talk) with the vocations director at the CMRI:
Vocations Director
Mater Dei Seminary
7745 Military Avenue
Omaha, NE 68134
Phone: (402) 571-4404
You're not committed to anything until you take vows, so don't get worried about talking. By the way, if what your family will "think" is an overriding concern, perhaps a religious vocation isn't what God has in mind for you.
