I try to upload a video every week though sometimes it is every two weeks.
Something to have in mind, you don't have to upload every day. Just think that every person only has a certain amount of time in the day that they will have free to watch videos and if you post every day, most likely they won't watch them all. I know that happens with me with some of the channels I follow. I just pick out the videos that will interest me the most (thanks to their thumbnail and topic). Later, if I have some time I may think I will go back and watch them ... but that doesn't happen in reality. There is always something newer or "fresher" to watch.
