As more women in the United States are working now, more are finding it necessary to make business trips alone. Since this is still new for many, some tips 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 they will enjoy the experience. If you will be eating alone a good deal, 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, get fully prepared what you will need in your travel as a businesswoman; this starts with lightweight luggage which you can easily carry even when fully packed. Take a folding case inside your suitcase; it will be very useful 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 ( 公文箱) so that you can keep the papers you need separate. Obviously, experience helps, but you can make things easier by yourself from the first by careful planning, so that right from the start you really can have a good trip.
