Choosy importance is reasonably hard to grasp. It refers to someone
who is vitally meticulous and critical. A persnickety individual often be fastidious and has high standards when it comes to standards and flawlessness.

Being persnickety is often associated with thorough attention to detail but can also be seen as a manifestation of pedantry.
