Fussy definition is somewhat hard to grasp. It refers to someone who is vitally selective and critical. A persnickety individual frequently be meticulous and does not settle for less when it comes to criteria and excellence. Their meticulousness can be regarded as praiseworthy, but it can also exacerbate unwarranted censure and avoidable dissatisfaction. Being persnickety is frequently linked to detailed attention to detail but can also be seen as a manifestation of pedantry.
