A Good Rule 

by Unknown Author

We have the wisest teacher, and she has
given this rule
That helps us in our lessons—you can use
it in your school.
Always add a smile or two when things
are going wrong,
Subtract the frowns that try to come
when lessons seem too long,
Then multiply your efforts when the
figures won't come right,
Divide your pleasures day by day with
every one in sight
Now if you always use this rule you'll
have a happy day,
For lessons then are easy, and the hours
fly away.
