Work smarter, not harder
Do not optimize for speed of execution.
Doing things faster will not result in more work done in the long run. (blue line on the graphic above)
Speed has limits. At a certain point it becomes dangerous, causing diminishing returns.
Instead, think how to automate a task, delegate it or simply make it irrelevant by reframing the problem. (green line on the graphic above).
A continuation of this.
