Effectiveness is doing things that move you closer to your goals. Efficiency is doing things (whether effective or not) economically.
Efficiency without regard for effectiveness is the default mode of humans, which is why we park our cars close to the gym, only to go inside and walk on a treadmill for 45 minutes.
Technology and automation make it possible to easily apply efficiency to tasks that don’t matter. To counter this, focus on processes and tasks that are worth doing because they move you towards your goals, and only then work to make them more efficient.
