How to do a mitzvot

They say you are to run to do a mitzvah.  Don't put it off when you can do it now.  Such was my experience today. I did just that. I went outside to smoke a pipe and noticed a box.  The 2 mezuzahs I had purchased for the basement area.  I took a minute and then put down my pipe and went indoors to work on the mezuzahs.  They are up now.  Look nice.   So, I'm going back to smoking my pipe.  And I might just run again.  Its a mitzvah to get a blessing of smoky enjoyment.
