Better the time spent now while you've got the time, than to leave them indefinitely and never finish them ever, wasting the time spent on them thus far.
Time is a valuable commodity that shouldn't be spent on unfinished projects.
Well, I guess you wouldn't be working on finished projects. You'll always be working on unfinished projects, but I mean each of them shouldn't be forever unfinished, or else it was a waste of your time.
I'm still single and have no kids so I probably have more free time than I think I do, so learning to manage the time I have is a lesson I ought to learn and apply to my own life...
