disease

As I donated another small amount today, I had an interesting thought. What is the right amount to donate? I recently donated to the Jimmy V Foundation for Cancer Research. Personally, I believe it is a better group to donate to; however, I fully support the 1 Second Film and other art projects. I also plan on donating more to the 1SF before the project is complete.

So, my question to anyone who may read this is how do YOU decide how much to donate and who to give it to? There are many "worthy" charities working to find cures for countless diseases. There are other causes, such as this, that I also feel are worthy. There are websites I frequent that run exclusively on donations. Unfortunately, I cannot give everything I have to each of them. What do you do? How do you do it? Most importantly, why do you do it?
