This ability to be focused on subjects and to discuss things in depth can definitely can be used in a lot of work situations, so it has its application.... I learnt to use it in the work I used to do with people.
Like you, in daily situations, I end up having people trying to stop me from going on and on...
its tricky - but I think reminding yourself before you start to talk that it is an exchange, and if they are NT, they are not going to have the willingness to listen to a monologue....even one that could be interesting...
the cues ... hard to spot when you arent doing much eye contact!
I still miss them now when I feel like a rant !
