> How can we achieve things with no burnout or ego-driven mindset?

First, let go of this need that you have to achieve things. You try and keep up with others, to be better than others, but it's OK to be mediocre.

Counterpoint though, in today's economy, people are forced to achieve and push for higher wages, just to keep a roof over their head. That's another source of stress and worry, and that's down to government and international economic policy to solve.
