Personal opinions:

If you're getting significantly more views than subscribers, you probably need to make some changes, but...

Keep in mind that some people will "subscribe" to you by bookmarking your channel which (as far as I know) won't show up in your subscriber count. They might also subscribe to your video uploads with a feed reader which, again, I don't think shows up as a subscriber. So keep in mind that your subscriber count isn't a perfect representation of how many people are actively keeping up with your content.

It's also important to take other statistics into consideration such as audience retention. Your meta data or promotion skills might be fantastic leading to lots of traffic, but are people actually watching your videos? Or do they get bored easily and leave? This information can be found in the Analytics tab of the Video Creators panel (in case you didn't know). If you need any extra help with that, feel free to ask

Above and beyond what is written above, I strongly believe that you have to love your own content and be proud of what you post. If you don't like it, how can you expect others to!? And if you ARE proud of it, flaunt it! Rub it in peoples' faces going, "Look at this thing I made!!" (Just don't get annoying with it ;P)

And always remember; good things take time! Unless you've already built up some sort of reputation elsewhere, it will take time and effort to build your online video empire. But keep up the hard work, and it WILL pay off
Good luck!!
