Congratulations, you have just chosen a specialization in
Constructs.
I could write a snippet about this, but I figure I said I'd tell you about it if you picked it, and that's what I should do.
Basically, from all your focus on trying to capture the moment just as it was, with all the emotional intensity you both felt, you got quite good at making your mental Sasuke seem lifelike. Granted, he only has the emotions he had in that short period of time... for now, anyway... but still. What you have preserved is more than a memory, even if it's still less than a full mental clone.
Constructs borrow a tiny fraction of your yin energy to mimic lifelike behaviour inside your head; they are most commonly used as part of a Yamanaka family jutsu I'll think of a poncy name for later. The basic idea of it is that when encountering a 3-5 group of mooks, career genin and the like, you trap them in your head the way your Dad did to you when he showed you his Matrix, and instead of the ninja waving to the guests, they wail the shit out of them.
Now tell me. What happens if you die in the Matrix?
Okay, okay, no, you can't kill people with your brain.
) But you can overwork their imaginations (read: yin reserves) so much that when you drop them back into their own heads, they'll
wish they were dead. You might even be able to get it to the point that you can put people into comas - your Dad can manage that in a fight, provided he only has to do it to one target.
It's basically Tsukuyomi as designed by a Spark.
But that's just one thing you can use constructs for. Sakura unconsciously uses one as a vent to get rid of her more problematic emotions and opinions, the Hokage uses his to honour fallen friends and 'get their advice', some ANBU or, formerly, KMP personnel use them to model their targets' behaviour or compare various pieces of testimony at once, and Ebisu uses his to practice talking to women.
O.O PLANS! TO CUSTOMIZE LESSON PLANS IS WHAT HE MEANT TO SAY!
tl;dr: The Fab Four better get the sofabed pulled out, they're gonna have company in your head.
You can still learn to do the other stuff, too, but constructs are going to be the easiest for you.
