I have aspirations to reconfigure the geopolitical balance of power.
No seriously though I'd like to be a consultant to some international organization, ILO, UN, or something. I know jack about US politics compared to my knowledge of other countries. I grew up here, but for some reason I find the politics incredibly boring compared to the issues in other places. That said if I was going to get involved in the US, like other posters I would do something related to municipal or even up to state level issues. There's definitely lots to do at the community level.
