Another planet signifying business is Mercury. It has a strong sign placement. Its house placement depends on your astrological taste. It can in be house 3, which is a bit on the weak side or in house 4, which is on the average/strong side. Your Mercury receives no aspect from Mars and a triangle (which is more beneficial) from Saturn. It also has the high ground, making their relationship more manageable and favorable for Mercury.
They say the devil is in the details and Jupiter isn’t very interested in those. You may be able to make big steps following your Jupiter-drive, but might not be able establishing lasting succes if you try skipping Mercury-things like the data and the numbers. Jupiter is more about the vision than the accounting. Pluto is the planet of hidden or subconscious forces, which might signify that you feel a subconscious pressure towards your Jupiter tendencies. This pressure might bring you further than you would have gone otherwise, but the other planets indicate that it is not without risk. I do not know about celebrities, but I can imagine a connection between their becoming great figures (Jupiter) through subconscious forces within themselves or within society (Pluto).
