Technically, 2019 is just a changed bit against 2018. So what should change for you?

The date changes every day. We're skipping days and month, wasting time, doing daily business and noone cares. But when the amount of years changes, everyone loses his mind. People start making plans for the new year, including changes for their habits and lifes. I don't get what it's all about new years resolutions. If I want to change, I don't wait for a specific bit to change, I just make a change, regardless of the date, otherwise I'd be my own prisoner. To be specific, I'd be a prisoner of the gregorian calendar.
