Compartmentalizing those Pesky Thoughts

In an attempt to keep my Mac organized, and mind clutter-free, I drag unwanted files into the trash bin regularly.  They are out of sight, out of mind.  I never, however, empty the trash.  There may be some remote need for the file in the future, I think.  Today, with some anxiety, I ceremoniously emptied the trash.  Even if I wanted to revisit something, I can't.  It's gone.  From now on, I'm moving all of those unnecessary, pesky and negative thoughts, which can sometimes consume my day, into the trash.  Then, immediately, I'm going to empty the trash.  Gone.  I just can't think that thought any more.  Gone.
