The rush of fresh year ahead of you is enough to get you started on new habits. But it doesn’t last. What matters isn’t how you start the year, it’s how you keep going when late January looms and you don’t feel like doing anything.
It can help to keep in mind that these concepts are just things other people made up. In reality, nature knows no months, it just goes through the regular cycle around the sun, perigee to apogee, and the 182.625 days in between are mirrored by the same number on the backswing around to the solstice.
Every day is a new start. No matter what, when morning comes, it’s yours to do with what you like. Start a daily habit or continue one, everything is always in motion. You might as well join in.
