If you're just doing this as a hobby OR your channel will mainly be about "you", your lifestyle, etc, then ignore the following.
I'm going to give you the advice I wish someone gave me before I started producing videos.
Your channel description: "Interesting (or sometimes maybe not so interesting but at least fun) videos about movies, tv shows, games, books, music, etc. on here"
Your first 3 videos are about 3 different topics. Multi topic channels can be slow to grow due to the YT AI having a hard time figuring out what your channel is all about resulting in low impressions and low click through rates. If you simply have to be a multi topic channel
then choose the 3 main topics
your channel will be about and start posting content related to those 3 topics only. Release several videos (3 or more!) about topic A, then B, then C, repeat, etc. It's important to stick to each topic for a while in the event YT starts pushing some of your content which allows you to ride that wave of momentum that typically follows.
It's VITAL to seed your channel properly which allows the YT AI to properly recommend your videos to the right audience which will increase your click through rate which will increase the odds of YT recommending your videos more often.
Down the road (a few 100 subs later) you can start introducing videos not related to your 3 main topics, but I would make the percentage 90% your 3 main topics, 10% random topics.
I will try to increase my upload schedule to one video per week
Reality check... long term, if you think you'll only be able to release 1 video a week at the most, you may want to change the channel to a singular focused topic channel, including branding, description, etc, etc, and just focus on making the best videos you can. Quality over quantity.
Don't get me wrong... can channels succeed posting 1 video a week, 1 video a month? Sure... especially the risqué, brash, off beat, strong political, epic how to, etc, channels. But for normal content driven channels like most of us here, it's a slow burn and that's why it's vital to understand channel optimization.
