Where Do Youtubers post 'about' making videos(NOT ADVERTISING)

Im not talking about self promotion I mean moreso where would someone post about what theyre writing about for a video, rn I'm working on a video breaking down breaking bad symbolism and the hook will be "What Does The 'pool' Mean in Breaking Bad"

anyways, Im thinking that It represents his ego/his sense of control over his life.

when he finds out he has cancer he's throwing matches into an already dirty pool.

(He's throwing fire into the mess/ his life is already thrown out of loop and he's adding to it but in a way that he is in control. also matchbooks are part of the process of cooking so Im assuming thats a part of it too as vince is like that.)

at one point hes cleaning a bloody bandaid out of his apartments pool, at a time that he's in an unfixable situation, the bandaid was brought by a stranger and walt is controling the cleanness of the pool the best he is able to.

theres more but id need the scenes pulled up to get any more in depth,

what do you all think of this idea?
