Sticky Authorship
There is a little emotional and psychological problem I call “sticky authorship” syndrome. When you create something — a web site, a picture, an application — you inevitably become its author for life. No matter how long time ago it was, and how perfect you are nowadays, you are still the author and your work still characterizes your professional level.
Since our past produce (as seen from the future) are always far from perfect, we are usually ashamed by its mere existence. And we desire to re-make it, despite of the absence of time to do that or the boredom we will suffer while doing that. Inability or reluctance to remake it causes stress and depression.
