It takes 3 weeks to form a habit, but it’s probably not enough to kill old ones

It’s 3as I’m writing this, and I know full well I should be sleeping now. I work in the mornings now, but suddenly, my body is still convinced I’m in Asia – it’s getting annoying. I’ve been waking up at 8 AM since I got here. Earlier even. Then suddenly, I started sleeping in the morning again. A lot has been said about building new habits, and I need to start listening to them again.
