There's a lot of great advice already so I'll just add: Create a bi-weekly, private email newsletter. Your biggest fear should be getting too heads down and building the wrong product or somehow losing the plot.
Create a newsletter for friends, family, developer peers, teachers, and anyone else you can think of.
Every two weeks you should outline what you accomplished in the last two weeks, what you're working on in the next two weeks and the plan for the next six weeks. The simple act of broadcasting the newsletter will help keep you accountable and focused. Good luck!
