     Here is a part of an E-mail answer from Joe giving some advice to his son in college.  

     When I was young, I often met troubles about what to do and what not to do. My grandmother told

me not to worry about those things. I only did once a year or once a lifetime. Instead, I should try to do

those things well, and I do them every day. For example, I need to eat every day, so I should learn how

to cook.  I need to talk to others every day, so I should learn how to work with different people and how

to speak well. I walk every day, so my shoes should be all right and comfortable. Every night I sleep, so

my bed should let me have a good rest. Taking care of the everyday things means that you do a better

job of  the one-in-a-lifetime things as well.
