When I first started (2013) I did maybe a video a month, sometimes two. I was not very serious about it, just sharing vids for friends and family back in the old country.
When YT asked me to monetize (2016?), I started to take it a little more seriously. I was posting two a week, then after a year or so, went to 3 a week. I did that for a couple years and got tired. Now I am back to two a week.
