A slight change of plans is possible

I will walk today for at least 15 minutes.  That is a plan that I intend to follow.  I needed to catch up on my exercise routine.  I know that today is a rest day since it is Tuesday, but there is no rule that says that I can't do this and I can't do that.  My health is a high priority and I am taking it seriously.  As I am typing this, I have a light bulb moment about editing my exercise routine.  I should have done that earlier, but it is really better late than never.  It is also better to be safe than sorry.
