Majority of programmers with some sense of pride would tell you they write the best possible code with uncompromising quality. Of course this isn’t true, and most of the time not even realistic. Unless you’re building software for a NASA space probe, aiming for ~90% perfect is probably the most cost effective.
My colleagues might consider me demanding (read: asshole) because I often criticize their code, but I’m not a compulsive perfectionist and I do settle for less than perfect solutions when it’s justified.
