This is the perfect answer, even including a good quote of Einstein
If after 6 months of regular uploading still everything is dead, big growth will very likely not happen unless you change something radically in your approach. Change the content, better Tags/title/description, more aligned with trends, make it more professional, etc but "just keep uploading, viewers will come" is not realistic.
I also think many people put too much weight on people commenting how nice your videos are and think they are on the right track. Most of the time those comments come from people with channels and are just there to lure you into coming over to their channel (S4S) even if they don't ask for it (if the subscriber has a thumbnail, it's usually already an indication it's a channel commenting on your video looking for a S4S).Keep analyzing your data, watch how other channels grow in your niche, keep uploading at least once a week and keep trying to improve your videos (and analyse if the improvement had an effect or not).
