E As more women in the United States move up the professional ladder， more are finding it necessary to make business trips alone. Since this is new for many， some trips are certainly in order. If you are married， it is a good idea to encourage your husband and children to learn to cook a few simple meals while you are away. They will be much happier and probably enjoy the experience. If you will be eating a good meal alone， choose good restaurants. In the end， they will be much better for your digestion（消化）。
You may also find it useful to call the restaurant in advance and state that you will be eating alone. You will probably get better service and almost certainly a better table. Finally， and most importantly， anticipate（提前做准备）your travel needs as a businesswoman； this starts with lightweight luggage which you can easily manage even when fully packed. Take a folding（折叠）case inside your suitcase； it will come in extremely handy（极其方便）for dirty clothes， as well as for business documents and papers you no longer need on the trip. And make sure you have a briefcase so that you can keep currently required papers separate. Obviously， experience helps， but you can make things easier on yourself from the first by careful planning， so that right from the start you really can have a good trip！
