Well, here’s one:

That feeling is called the "Real Programmer" syndrome as named by a post that went crazy on Reddit last week. The Real Programmer lives only to code. Redditor big_al11 explains:

A Real Programmer is someone who loves programming! They love it so much that it's what they spend all their time doing. ...

…

That programmers are expected to work insanely long hours isn't new. But this idea that they are doing it of their own accord, for the sheer joy of it, is new. More.

One problem is, they may end up thinking that everyone feels that way about their work, and design systems accordingly.
