What: Henry David Thoreau
When you’re not in for the money, success doesn’t come to you pre-labeled. It can look just like failure. Chasing money makes it easier, because then you can quantify success unambiguously. Otherwise, you may have a hard time telling the two apart.
You can work on a lot of projects, but you will only get a couple of opportunities to work on something long-term. So I would say pick those carefully, do things that are intrinsically rewarding, and be very loath to abandon them.
