Possible Impact?

So, I was talking with Adam about what kind of impact he thought the Junior Fellowship Program could have, which got me thinking about how I feel about any possible impact I might have.
Before I jump into it though I figure I should give a bit of backround about my own placement, I'm going to be working in Pagazaa, in the Northern Region of Ghana, for the Africa 2000 Network trying to create a more efficent office environment and skill building among the empoyees of the Shea Butter Project.
I think I look at the JF program in two ways, firstly it offers young people a chance to learn about poverty first hand, and secondly it gives us a chance to "set the table" for greater change down the road. Since only real, sustainable change can occur with time and by those people directly involved it would be niave to assume that in 4 months I could create any significant impact. By my "set he table" analogy, I mean, I hope that my work, perhaps for example by helping co-workers at the NGO with their computer skills, that they are in time able to use those skills in some way to create true change in there community.
That's all I got for now, as always thoughts, comments, and criticisms are welcome.
Cheers
