I'm glad you replied, as it wasn't intended to be arrogant. Some people care about the end result, not worrying about how it gets done, as long as it's done. Others care about the journey, perfecting their art at every stage, with little consideration for the end goal. And some people are able to balance these things.
Have you ever looked at the source code of a dependant library, followed by an overpowering and compelling urge to write your own from scratch? Suppressing the urge to rage quit because your tools are fighting against you, not with you. For me, it is a constant daily fight to force myself not to do things "properly", for it's mostly an unrealistic and unachievable goal.
Believe me when I say that being a perfectionist is nothing to be arrogant about, and despite it being one of my major strengths in some ways, it's also one of my biggest flaws.
(I'm taking it on faith that you're not trolling, and have taken time to give an honest reply)
As opposed to those who prefer imprecise, flawed and ugly solutions? Jesus dude, could you possibly come up with a more arrogant sentence?
