Are you sure you have 30 years after that. You don't know if you even have a week, anything can happen. This is why I would not spent all my time working and push the living for later on.
My parents had their own business for years and it did well but they gave it up for living their life rather than spending all of their time at work. They have less money now than before but they are also now happier than before and get to spent months off work travelling and evenings and weekends together doing whatever they want.
Also you can work hard even if you do 40h a week. It doesn't mean you don't have enough money for a nice retirement time or that you will end up with nothing.
What comes to that funeral comment... No offence but it sounds horrible you to say something like that and a little bit like you don't really care about this person. I could obviously be wrong about that but this is how you make it sound.
There isn't one right way of doing things but I personally wouldn't put work in front of my life ever. That doesn't mean I don't have ambition for anything or that I wont work hard to get something I want.
