Hello All;

So I recently launched my channel and its very rough around the edges, but that will be ironed out as I get into the groove of youtube and production. My interests are Movies, Gaming, Personal Growth and soon weight loss journey. My questions is the most successful channels require you to fall into a niche, so just one of those interests. I would love to show and discuss them all. Would it make more sense to have 1 channel that's all over the place or a channel for each? More channels would obviously mean more work overall, but I would rather do more work to reap bigger rewards than do an all in one and it doesn't go anywhere. Thoughts? Is one channel with different playlists of topics doable and growable?

Thank You for your feedback, have a great day!
