N is for Necessary

Only purchase NECESSARY items for your business in the beginning.  Sometimes people spend too much getting all the whistles and bells then can't make enough to pay it all off so they go under.  It is difficult when first starting up to not want to get everything.  Trust me, if you don't have tons of "playing" money start out simple.  Save money and once you are operating and able to pay for everything then purchase some more bells and whistles.
