1. I don't know if this is what you had in mind when you were referring to a "line in the sand" but perhaps the "kabolos" can be "asei tov", action variety to something positive in the area of GYE/shmiras eynayim and shmiras habris..
Just a few suggestion maybe to read a "selection of the day" from the handbooks
Or make a kabbalah to post encouragement or pm chizuk to another member on the forum, everyday!
