I was used to working long hours.
I got used to working long hours.
What meaning do the verbs be and get have here? My textbook doesn't explain it. But from the examples they're used in, I have an impression that get emphasizes that there is some transition between one state and another. For example in my sentence got used means that I was not used to it before but then became used to it. While was used doesn't imply that, maybe I was always used to it.
And this usage in Present Simple:
I am used to it.
I get used to it.
Does get imply that however I am not used to it at the moment but I will be used to it soon?
