My job created the biggest amount of imposter syndrome for me, it's something I feel like I weave in and out of frequently, though I've been doing it for 5-6 years now and rather successfully. The amount of knowledge I don't know yet keeps it coming back.
Musically it's slightly different, but I don't disagree with a single thing he said in the video. I've been trying for the last 3 years to get back to the creative spot I was in when I first built my home studio and was writing like a maniac, I was addicted to it and these days I have to drag myself to the studio where I can't seem to come up with anything that compels me to continue working on it. Some of the things he discussed in the vid I've already gotten around, but it still feels like the well is often dry.
Friends and family have been telling me for years to do something with my YouTube channel and I'm certainly not driven to become a YouTuber, but last week I renamed my channel to Sometimes I Hate My Guitar and the vid in the OP is really where I want to focus the channel, discussing the things the keep us away from utilizing all the year's of effort we've put into music. I'm hoping it can be a 'learn with me as I figure my own shit out'
