You don’t have to do maintenance if you don’t have any assets….

I remembered to switch to a freshly charged drill battery before going clear across the building.

I don’t know how many times someone's used my drill and spent 99% of the charge, Then I get under some table clear across the building to find out its DOA. 

“Oh, the Save button BEFORE the back button after adding all those tasks to the SM!”

You don’t know, what you don’t know.
