When people ask me this question or say that it is easy to sit down and keep typing; I ask them the same question in their field and then they explain how exhausting or hard their job is.
Then I just try to link my pain points with theirs.
As they explain their process, we are already in the tone of understanding each other and can relate easily to the pain areas.
With their explanation of their problems, they already gave you the words and pointers to use again to explain in their vocab.
