No it's not too late, but since you've mentioned you want it to create a passive income a few points: 1) Youtube videos require SEO just like a webpage. You need to create backlinks to your video and maybe send some traffic to it to make it relevant. Brian deen has some very good videos on it. 2) Pay attention to the engagement metrics, bounce rates etc. It matters a lot for getting your video in search results. 3) Invest some time in peripheral things like a good thumbnail, video optimization, etc. The more clicks you get the higher it starts ranking. 4) Last but not least monetising video based on ads is not where it's at. Most successful Youtubers are often making more money with affiliate marketing (most) and sponsorships. So when you want to create content for Youtube make sure your priorities are clear. Are you doing it to generate income or is it just a hobby. There are very different approach to both.
