Don't call ToList() 

Lets say we are doing something with Entity Framework Core.
Maybe pulling some data and "hydrating" some objects.
Think twice before calling ToList() in the middle of the action.
We are likely doing it wrong.
Maybe we need to tweak the data model 
or maybe we need to adjust the query 
but we probably need to do something.

STOP. 

Take a look at what we could do differently. 
Even if the query is fast,
what if the number of results is 1000x?
