You make it sound like I implied that one should life their life nihilistically or with indifference - I definitely do not think one should do that.

I thnk there is most satisfaction in putting yourself 100% into whatever you do. But what you do is not strictly limited to your work.

Sometimes you put yourself 100% into your family, sometimes it is education, and sometimes it is work.

That's fair, but my point is: Irrespective of whether you put 100% or 20% into your work, you should do some planning of your career so that whatever percentage you put into it is reasonably spent. Even when you just plan on spending 10% on your work, planning where you want to end up makes sense.
