what is a worthy charity?

I spend a large chunk of my time on earth, helping people to do things that I believe to be ( the List ) foolish, naive, self-defeating, self-destructive, or just plain pointless ... because it is simply what they want to do, and I have the spare time to do charity. 

It probably comes from an enjoyment of my excess time alive, as well as the chance to provide others with opportunities to fuck up under their own volition, which I didn't feel that I had as a kid.

Generally I have to risk-manage against the following :

1. people who welcome help, but not if a help thinks the helped are on the List

2. the helped, who do not mind being thought of as on the List, as long as the opinion, that the helped are on the List, is not too loudly, or too often, spoken; some of these helped trying to get off the List, which is quite understandable 

3. people who will modify their interactions with me, because they feel that I am wasting my own time

4. etc. 

Strange, what we all do with our objectively pointless time in the conscious universe.
