There are days when I have great thoughts and I think to myself, "Hey, those things would make a great article!" Only trouble is, when I sit down to write an article I can't remember them.
My writing coach, many years ago, told me, "Tom, you should carry a small recorder in your pocket and whenever you have a great thought, put it on tape."
Today there are recorders that don't even have tapes. They work on memory chips instead. Well, I don't have either one and old age is setting in. I would probably buy a voice recorder when shopping if I could remember.
