When I was much younger I worked on an eco tourism project in Laos. The only westerners in the town were this ecotourism co, and NGOs.

Every year a new NGO would get some funding and turn up to do something, buy a bunch of cars, fund a bunch of office workers, deliver something like lay a road or teach about sanitation or STDs or whatever, then run out of money, pack up and leave.

Every year the ecotourism project made a profit, reinvested in the community, and just kept plugging along as the NGOs came and went.

The founder was very straightforward about it. If you want to add value long term, you must have a profitable business. There is no other way to do it."

Lesson in there.
