Continue or Drop?

I've been writing this novel by both improvisations and having various goals in mind (e.g. future scenes and building up to them)

The thing is, I'm not exactly sure whether this novel is worth continuing or not. It's fun to write, but I just can't tell whether it's good not. It's not obvious to me, the Author, because I'm obviously going to be biased, so I'm relying on whoever bothers to read this to tell me.

In case it wasn't obvious, my self-esteem is utter crac when it comes to this type of stuff.

Well, yeah, that was it. If there aren't any comments or anything relevant in the next few days, then I'll just drop the novel.
