As a data professional, you are likely consumed with data in the same way a music professor is consumed with notes. When that scholar teaches a class, they can’t just spill out every single bit of detail they know. An enormous infodump would be overwhelming, and it would probably turn students off, especially younger or non-major students. Good teachers consider the knowledge and needs of their students. 

Similarly, it’s crucial for you to set aside your own immersion in the data and ask the questions: What does my audience need? How often will they look at this data? What do they need from it? What do they already know about this subject? Have they used dashboards before?
