Does anybody have an idea in terms of neurotransmitter balance, which of the Neurotransmitters are the players in the difference between the consciousness of focus level:

1. Example: like being able to organize a pile of the smallest nuts and bolts for three hours and not take a break.

2. Example: Trying to wash dishes and stopping every 60 seconds or less to either text some one, research a topic on computer of your ongoing mind chatter, and looking outside of your window and or talking to your Cat.

Anyway you get the idea.
Some of this has to be trained like a brain muscle.
But some of it is a result of a direct proportion of neurotransmitters in you.
And of course there are lots of sub factors like lesser controllable variables like"distractions".
