Well said. The most industrious are those who live their lives by some form of checklist, and manage to at least check some of the items off. The only problem I have with checklists are those who obsessively try to achieve each task on the list and presuming each item is somehow not complete unless the others are completed.

A little known phrase that should be tattooed inside their skulls is "opportunity cost" which I learned from Mark Manson's blog, and it is a great phrase. Try to read "No you can't have it all".
