Not to alarm you but it's very important to keep an eye on your analytics because it provides a better understanding of who is watching your video. If you know who is watching, you can make more targeted content which will increase your viewership. You don't have to be vigorously hovering in your analytics tab every hour of the day lol but if you see a video on your channel doing better than the others, go check the analytics to see who is watching, how they found your content (search, suggestions, homepage, etc.) and retrace the steps you took making the video to try and identify why the video is so popular. Or if the opposite happens, and you aren't getting any views try and what's different. It's just a tool, and tools make your life easier. You can choose to ignore it, but even if you passively try and understand the information it gives you, you'll be better off.
