Fussy importance is somewhat difficult to understand. It refers to someone who is exceptionally picky and fault-finding. A persnickety individual tends to pay strict attention to detail and does not settle for less when it comes to standards and perfection. Their fastidious nature
can be viewed as laudable, but it can also exacerbate extreme disapproval and avoidable dissatisfaction. Being persnickety is regularly connected with thorough attention to detail but can also be seen as a manifestation of pedantry.
