I think it was a good way to introduce the notion of living for positive impact. And it is certainly helpful for people who feel like they "aren't doing anything good with their lives" to see ways in which they maybe already are, or could be.

That said, it felt a bit "all of nothing" in the sense of picking a single strategy for impact rather than trying to be impactful all around. There is probably a place the the "7 habits of highly impactful people" piece somewhere.

The final bit that I'd suggest would be having an impact without drawing attention to yourself. A number of really great people I know do wonderful things without having to deal with the issues of public accolades. A friend of mine who became wealthy though Sun stock and good financial management of it, made the mistake of donating directly to an organization he wished to support. And while the donation was not considered "large" by him, it was the largest donation this organization had received so they put a big thank you in their newsletter. And that resulted in literally thousands of other organizations pestering this poor guy for donations. Ever since that time he has made is impact less direct and harder to trace back to him.

It walks a very fine line though, between a person believing what they are doing is helping and outside validation that it actually is. Fixing that communication channel would be big win for getting more participation.
