I voted 3-5 years, because I have a 5 year study plan, but I feel kind of apathetic about it. I have the same problem as raincrow007: nihilism. At the moment I am not very fond of the future, on my own part anyway, because I see nothing else in it but fear.
I think by the way Ni is more realistic than Ne, Ni also being more future orientated. Especially coupled with Te it is a lot more realistic than Ne. In general I find xNTJ to be by far the most realistic of the iNtutive types.
Coupled with Fe it seems to me like Ni might be kind of dangerous to a person. In a very emotional state Ni might give some rather unrealistic insights, which the person who has them becomes very certain of. I certainly see it in my INFJ mom, who is not very emotionally stable and constantly worry about the future and often is being paranoid without reason.
