I've pretty muched stopped proselytizing about the benefits of miles and points.
Of the several people that I work with, all who travel more then me, only one took the FT idea to heart. He recently took a two weeks vacation to Scotland and England, free airfare and free hotel. That was after a year accumulating miles/points during business travel. He doesn't even visit FT, he just checks the the websites of the programs he is in and will ask me every once in awhile if I have heard of any new promos.
The rest are too busy (but you can spend an hour on the phone with your mother talking about cousin so and so) or it is too complicated (I've told you I would forward on all the good promotions, you just need to sign up) or you don't travel enough (wait, I just barely make SE on NW and you travel at least three times as much as me) for those people that can't be bothered, I figure they are too lazy to help themselves so I am not going to go out of my way.
I am partially Ok with those who choose not to partake... it means more for me. Although I am still saddened by their lack of interest for a couple reasons.
1) The lack of initiative many times translates into other areas of their life... like work for instance.
2) Some seem to actually have a fear of travelling, not the flying but going someplace new, risk of putting themselves in a situation that they might have to expand their mind to deal with another culture.
I think the second reason is the saddest.
