The more conscious I am .. or the more thinking thats going on up there the slower Ill have to go.  When my mind is in that state its usually when trying to get something worked out.  But its a good thing When learning something.   Theres some topics on here with a brainjo title that adresses this.  Basically the points that were trying to be made is you have to connect the subconscious brain to muscle memory ( a term for lack of better one )  Rest.. try again next fay so on so forth.   at some point those connections are made and you DONT have to think about it or talk yourself through it.   

Being relaxed helps.   Not doing too much also.   focus on as little as possible... so dont try to be learning too mich at once.

Maybe not what you meant.   but yes..i do..things like ok.. this is the measure i need to make sure and slur here to here... or.. this is where i let my 4th finger stretch too far ..or not far enough... or open E coming up..remember to go easy when you hit it. ..whatever..things like that.   Or.. omg.. im a step and a half out of tune to everyone else..get quite quick!!! 😆  thats when the whole train derails .. happens.
