I think why people don't really change is not that they enjoy the state they are currently, but the subconscious mind doesn't allign with you to change. It's only when your subconscious mind allign with you that's when you can see change. It's the subconscious mind that will tell you "dont you know when you change you will loose it all" or " when you change many people around you will leave you" maybe you might fail when you change. Those thoughts will make you to start to reconsider. My thought.
