“The procedure is quite simple. First, you arrange items into different groups. Of course, one pile may be sufficient, depending on how much there is to

  • do. If you have to go somewhere else due to lack of

facilities, that is the next step; otherwise, you are pretty well set. It is important not to overdo

  • things. That is, it is better to do too few things at
  • nce than too many. In the short run, this may not

seem important, but complications can easily arise.”
