Helping others doesn't have to be physical. Preaching about all talk no action seems a little oxymoronic, is that the right word? Showing someone how to take action is proly more effective. I have been helped by many on this site just reading and researching, that in turn lets me help others. Small example.
I live in a small town with a few weed dealers with expensive buds that need to be brought in. Now that I've shown a bunch of people how to do it themselves they have shown others and there is rarely a need for dealers. So a couple dozen have been helped but again there is a few who had to get a job so they could buy buds from my friends.
