Author here - thanks for the kind words. I mostly agree with your comment, the problem is less of not being able to achieve targets and more of the number of targets increasing as you get more and more ideas to add to something. Do start a blog, it's really fun!
(Author here) Yeah, most of my personal projects don't fall in the never-ending category either, this writeup was more about the ones that do because you get so many ideas as you work on them that you keep working on them.
Very true. (Author here) I think I was just trying to self deprecate to be funny, but deep down I agree with you, even though I have no clue how certain things I spend my time on will ever help me.
Edit: Adding your comment to my favourite quotes list, you put in words something I kinda know but had never seen said articulately before.
I'm always surprised by how often advice from extremely successful people tends to repeat itself, which tells me that there really is no "secret" to making it and living a great life that I don't already know.
