Not changing is fine if your circumstances are constant. But are they ever constant? Our bodies slowly deteriorate day-by-day. We could lose our job. Our partners could leave us. We might get ill.
Change is inevitable. Even if you stand still, life won't.
Yin/yang is about exchange. To get something, you have to give something. You have to do something.
It is believed that laziness is a biological trait. A survival tool. In itself laziness is not necessarily a bad thing. People often see/hear the word 'lazy' as being a stigma and get defensive.
Imagine that you're a primitive human living in a valley 10000 years ago... The valley has all that you need. It is safe. It is free of hostile predators or rival tribes.
There would be no sense in going elsewhere. This is laziness. A desire to maintain the status quo. Not to change.
