Should i focus on mastering one medium?

I've been struggling with this for a while now.. I mean, I love experimenting with different painting and drawing techniques, but at the same time, I feel like I'm not really getting anywhere because I'm spreading myself too thin?? I've been watching a lot of videos and tutorials on various mediums, from watercolors to oils to pastels, and each one has its own unique challenges and rewards... but is it better to dive deep into one or two mediums and really master them, or to keep exploring and trying new things?? I feel like if I focus on just one medium, I might get bored or stagnate, but at the same time, I don't want to be a jack-of-all-trades, master-of-none... does anyone else have this problem?? how do you balance experimenting with different mediums with actually getting really good at something?? I've been trying to set aside dedicated time for each medium, but it's hard to choose which one to prioritize... and I guess what I'm really asking is, what's the most important thing to focus on when you're still figuring out your style and voice as an artist... is it the medium itself, or the overall message and emotion you're trying to convey??
