26.0 Hero Projects: You'll have to do it someday
An "hero project" is a project that you personally think will solve a large group of problems at once. It could be a different architecture, a new framework or even a new language.
That means you'll spent your free time to write something that is already being worked/exists just to prove a point.
Sometimes it proves you where wrong.
(But you got something from it, nonetheless.)
26.1 Don't confuse "hero project" with "hero syndrome"
I have seen this at least two times: Someone claims things don't work when they aren't around or that they don't need help.
This is "hero syndrome", the idea that that person is the only one capable of solving all the problems.
Don't be that person.
