I have Neptune in second house in Capricorn and for me is a difficult position because I tend to idealize my life in such way that reality doesn’t come close to the things I dream about. I have Neptune, Saturn and Uranus together in the same house and sign and in t square with my others planets. I don’t know if it helps but I think that Neptune can be elusive and so fluid that one can easily lose focus. The second house is the house of self value and material resources , so I can understand why’d think that’ Neptune has something to do with your money management skills. I can control my spends but I’m no good in deciding my work field. I escape from the world for long periods of time. Hope to have helped you in some way. Sorry for my English I’m from South America.
