By a similar note, I'm working on a pet project, with no commercial aspirations, but, yea, it would be nice if others eventually use it.
And by that notion, I have lots of ideas, but I must continually consciously reign myself in and try to not fall into a hole for a "nice to have". I don't even have a "have" yet, and would be good to get that finished before we get to the "nice" to haves.
But, I whittle away, pushing another quarter inch forward on my 10 mile journey. I still find myself stuck in a featuritis pothole now and again.
Having a destination document can help keep you on track.
