Like they all said ^^^
By definition
Insight means:
the capacity to gain an accurate and deep intuitive understanding of a person or thing.
Really any documentation of what's happening around the world, trying to understand and live in this world is insight.
You gain insight by going to a Bible Study, church, which can be used around this time of the year with Easter approaching - Passover, Lent, etc.
Trying to understand the mind of a child is also insight.
The one thing that I learned a couple months ago is that you DON'T have to use the word on your layout, but draw inspiration by the definition.
