I think humans prefer to live on autopilot. Life is easier when you are familiar with your surroundings, things are predictable and you have developed habits that work well enough. When you introduce change, you force others to re-evaluate the new situation and to establish new habits. That requires active thinking, choices. Those take energy, and you feel more drained afterwards. I believe that we optimize for stability and not change, because we aim to spend as little energy as possible on getting through our day.
