David Steffen: I find the endowment system in the Runelords series particularly interesting, where a donor or "Dedicate" can permanently grant an attribute to a recipient or "Runelord", and that link lasts as long as they both live.
The small 'Dedicate' fleet serves oil-industry destinations in Africa and the Arabian peninsula, their cabins equipped to high-end business-class standards.
Dedicate a day or more helping out in the community.
Dedicate your downtime to just one or two activities instead.
Dedicate some time to watch the finale of the Oprah Winfrey Show.
