> Grinding to make money in your thirties and beyond

I sort of think grinding is generally wrong at any age. If you feel like you're grinding, perhaps it's time to take stock and consider what you could be doing differently so that you don't have to keep grinding to both meet your responsibilities and enjoy life. Of course some might find themselves with enough exigencies they have almost no choice but to grind, but I doubt too many people on HN are really in that boat.
