I ran a YouTube channel posting video editing Tutorials. Put a lot of effort into it as a teen. The channel is RobertDoesTutorials if anyone wants to check out the stats to gauge how much time I put in for the views. At its peak the channel made me about £30 per month from 20k views per month. I haven't uploaded in a long time and the channel still makes money but has slowly tapered down over the years to about £10 per month. Not a huge amount but I probably could have scaled this more if I continued to upload. Defo a lot of potential with YouTube but it takes a lot of work
