The Value of the Word "No"

My back burner is overflowing.  Every time someone needs help, mentions an interesting seminar or a worthy cause, I would jump right in and take part without hesitation. As a result, I am working, planning a trip, attending classes, signing petition, and such and such, ALL the time. I barely have time to eat. I don't have time for lunch often.

I must start to use "no" more often.
