Top rated inspired self appraisal short story with inspiring man cutter who cuts lawn.

A little boy went into a drug store, reached for a soda carton and pulled it over to the telephone. He climbed onto the carton so that he could reach the buttons on the phone and proceeded to punch in seven digits (phone numbers).
The store-owner observed and listened to the conversation:
Boy: "Lady, Can you give me the job of cutting your lawn?
Woman: (at the other end of the phone line): "I already have someone to cut my lawn."
Boy: "Lady, I will cut your lawn for half the price of the person who cuts your lawn now."
Woman: I'm very satisfied with the person who is presently cutting my lawn.
Boy: (with more perseverance) : "Lady, I'll even sweep
your curb and your sidewalk, so on Sunday you will
have the prettiest lawn in all of Palm beach , Florida."
Woman: No, thank you.
With a smile on his face, the little boy replaced the receiver. The store-owner, who was listening to all this, walked over to the boy.
Store Owner: "Son... I like your attitude; I like that positive spirit and would like to offer you a job."
Boy: "No thanks,
Store Owner: But you were really pleading for one.
Boy: No Sir, I was just checking my performance at the
job I already have. I am the one who is working for that lady I was talking to!"
