Ask HN: How to fight listlessness and depression due to work?

I just fail to see why people at my workplace fight over petty issues. It affects me personally that people would be so short-sighted and not see the bigger picture/impact of our work.

At previous workplaces we saw how our work benefitted millions of people(I worked on y! mail) and I was happy being a part of the team.

What has affected my work most is, beyond earning a paycheck, nobody cares. They’re all content and I am the only one who wants to change systems for the better.:)

Obviously this might not fit well over the longer term, but beyond moving to a better workplace, what are some of the tricks you’ve applied to navigate such a workplace where everybody seems to be complacent and not invested in their work as much I seem to be.
