It's hard to do the work that no one told you to do.
That no one asked you to do.
That no one will ever check.
That you're not getting paid for (initially or ever).
That doesn't have a deadline.
That you do just because you want to do it.
It's hard to do this kind of work.
And it's even harder to persist doing this kind of work.
But at the end of the day it might be the only work that really matters...
