I suppose, yeah, when I figure out the exact reason why the error occurred, fixing it is often easy. The finding, however, can often take a long time, which leaves me feeling "once you have driven across the continent, finding your desired endpoint is a quick process". "Once constructed, installing the door on your new house is a simple and easy task". Well, sure, if you take out the time-consuming parts, it's quick and easy.

Except for all those runtime errors where the fix required major refactoring, or the problem is in a third party library, the OS, or some other unchangeable component.
