Corrina,
We'll have to chat offline sometime. I was Manager of Writing Services at WV and it was a constant balancing, considering the quite different needs and perspectives of the promotional/marketing division and the program staff in the field. Their mission was most important, of course, but they couldn't do it without the grants and other funding we brought in.
I learned so much at World Vision it is difficult to choose one thing, but I guess I have to say the people skills and the customer service ethic. 6,000 projects in 126 countries, phones constantly ringing, getting up at 1am to go to the office (this was in Los Angeles) to conduct a phone interview with a project manager in Senegal, that sort of thing. And I learned to respect and meet deadlines.
I think you'll do great running your own business because you undoubtedly picked up skills like that, too.
