I haven't done this but I've heard of it and known people that use things like the "tool box." And what I learn is this: Most people don't care and don't want to help you. If you give them your "tool box" or wahtever they just tell you it's your responsability to take care of yourself. If you tell them you may be in crisis they will tell you it's not their problem.

So, although I think it is valuable, i also think that so many people don't want to help others that it becomes difficult to use.
