That for most people here means probably to work even more, but just coding what they believe is significant, when you feel with the right energy, and not what the current company / job believes it is.
I believe there is a significant amount of people that every day wake up and go make something they believe it is useless, just to pay the bills. Richness can stop this massive personal sacrifice.
Clarification: As you can guess I'm very happy with my current job, the problem is, I wrote useless code for many years when I started to pay my bills as a programmer. Later I created companies and I was able to escape the sadness of writing useless code. However the fear of returning into this condition is always present, especially with a loan that I used to purchase a new house, children, and so forth.
