Reached an old post at Tim O'Reilly's blog titled Work on stuff that matters: First Principles from one of Aaron Wall's posts. It is strongly worth a read. A couple of great quotes in the post, the first one below
Money is like gas in the car -- you need to pay attention or you'll end up on the side of the road -- but a well-lived life is not a tour of gas stations!
The other is with reference to a poem by Rainer Maria Milke which is quoted as
What we fight with is so small, and when we win, it makes us small. What we want is to be defeated, decisively, by successively greater things."
