And also in thought on "typing moment of" as in thoughts being typed can seem quite a bit requirement of dechiphering of whats going on when doing multiple things. An Ideal point that I do not seem to grasp very well is to single out any project and state direct view...

Use your own pace even if it leads to exasperation is one phrase I still hear to this day.
