Try to release the game before moving on to the social app. If there's one thing I regret from your age (and later), it was not making shipping my priority.
Agreed. Ship it for the sake of shipping it and using it as a portfolio piece. I remember one app in particular that I spent a LOT of time on including meetings with others, etc and I never launched it. It still makes me mad and haunts me.
So if you're close to launching the first app, launch it for the sake of launching it and seeing a project all the way through.
