While Uranus is connected with both the now and the future and bases future trends on what’s happening now; Neptune sees beyond those future trends.
What Neptune sees is baseless to Saturnian beings. Neptune doesn’t base future trends on current happenings. What Neptune sees does not currently exist but it will eventually.
Strong Neptunian natives see trends way before most people even have an inkling about them. In fact, other people might think their theories and visions are crazy because it’s not packaged in today’s materials!
Neptune in the 10th is at least 10 years ahead. Neptune in the 10th is a visionary of Future, Future Trends.
If you have this placement, consider a career in forecasting or strategy especially if your MC or Neptune is in Scorpio! ;P
Also take a page from Uranus and try to reel your predictions in to what the people can use today and in the near future while nurturing your future, future predictions for those people and organizations that are very long range planners (Virgo opposite Pisces!).
