Good advice above. I'd just add that goals, like bikes, come in all shapes and sizes. You can have a goal of reaching 1000 viewers. Or to capture your next trip with videos you'll be proud to share. Or to use it as a motivator to get more involved in the larger moto community. All valid and reasonable goals, IMO.
Me, I tend to be a little less goal-oriented, and think of it a little differently. YouTube production is one of my many hobbies, but it is one that I can potentially tie in with my other hobbies. It's also one that I can apply to non-hobby aspects life: for example, I use my photography and video skills to help my wife with her side business, I'm trying to get better at documenting our family trips, I've done photos and videos for my son's hockey team, and am considering branching out to offer them as services to local bands, etc.
So, in order to be able to maximize the utility of my photo/video skills, I need to keep developing them. To that end, every time I do a video or photography project, I have two goals: creative and technical. The creative goal is to make the best, most compelling (or informative, or inspirational, or fun, whatever) video that I can. And the technical goal is to learn some new skill or technique that will benefit all of my other video and/or photo projects. So far, every video has met at least one of those two goals, even if it has failed to move me toward say, 1000 viewers. As long as my pool of skills keeps increasing, that alone is a worthwhile goal. The other ones (viewership, etc), are all secondary, "nice to have" goals. Maybe at some point that equation will change, but for now, it works for me
