Jan 1st is the beginning of deep Winter the time when you should be resting and nourishing your roots.
To try to “begin again” on Jan 1st is suicide and utter stupidity.
Many habits in our society are stupid, don’t follow them.
Spring is the new year, hence the name “Spring”.
Rest and nourish your roots.
The origin of Jan 1st new year is mankind’s hopeless attempt to “defeat nature”.
And this is due to his misunderstanding that nature is against him, it is not.
You are nature.
