     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.
