It’s an arbitrary day on the calendar, yes.
I want to grow as a person, in terms of character and ability. My desire to evolve is a product of curiosity and vitality and ethics, not some capitalist mania for MORE.
Putting a random day on the calendar where I tell myself that I’m at an inflection point, that I’ve decided to bend my path, it’s useful. There are religious holidays where you atone, forgive, and so on. Those are also just days on a calendar. But they serve a purpose.
