I have this problem while acting, Im anaylising myself in real time if this is the right gesture, How is the way i look, Am i using a natural voice, Am i sounding fake etc.etc. No matter how many plays i do no matter how much i face the camera it just doesnt go away... I can't be present in the scene, Even after trying so hard And in the end when im done performing i feel so disappointed, But the outcome is always decent or good enough but im never satisfied, and i hate myself for this i feel like a failure

I have been playing guitar for a year or so, Am i four chords guy, Know some barre chords too, But have no idea of scales, Progressions, Note placements on fretboarda Recently started watching videos and trying to understand music theory

Can someone give a roadmap of how to learn things the right way?? im using youtube as my source, Don't have dedicated time for guitar classes How long can it take before i get a decent grasp of how things work in a song? And don't have to watch tutorials to find chords of song?
