Margin is the opposite of overload. If we are overloaded we have no margin.
Practicing some my math questions with my daughter:
If you give someone $1.00 for an item that costs $0.79, how much change will you expect back?
Her: 20 cents.
No, it’s 21 cents.
Her: But how are they going to give me the penny when it doesn’t exist?
When I told my daughter that the groundhog saw its shadow and that meant six more weeks of winter, she was actually excited about it. A sure sign that she’s not growing up in -40 C winters that last forever like I did.
