I'm interested in personal forecasting - predicting my own future behavior on a range of timescales. I see it as a more useful skill than forecasting on world events. Formulating personally useful forecasts seems like an important and neglected skill in the rationalist community. And it would be nice to have some company, and tools to make it more convenient. Right now, I'm just using a spreadsheet. Does anybody know if there are groups doing this sort of thing? Is there a good app to manage the process?
