Pocket pens and paper

As my memory weakens but I find increasing numbers of important or interesting things to remember or do, it is helpful to habitually carry pens and paper.  I like to take a piece of scrap paper, usually something printed on only one side that came in the mail and fold it into eighths.  I have room in my pocket for two small pens.  I carry two in hopes that one will work.  Often, the pen won't make a mark.  I think it comes from something rubbing on the paper that make the paper hard to use a ballpoint on.

I haven't actually used my pocket paper much but I am training myself to question if making a note would be helpful.
