How should I release my first product?

Currently I am building a social network. But come on, who needs a new one that isn't special. I have some ideas, but I am not sure which ones to add and how to monetize my final release.

Some more info: I am 16 years old, have much time and can code pretty good. But I struggle with putting my first product together. I always build the base of the product and then I stop coding, because I am scared of releasing such a big thing by my own.
