not pulling this out of my ass. most people who start something new around the holiday and new years season aren't committed.
Most people don't have enough willpower for anything, generally speaking. That's why there are superiors who yell at you all the time in the military. If they weren't after your skin all the time, you would probably become lazy.
The key is trying to be in the minority who follows through. This minority exists, though out of shame with our own failure, we like to deny it.
I've found that using an app for tracking your behavior helps. I would recommend the Android app "Habits". It is important not to lie to yourself and have accountability.
Whether you begin at the end of a year, in the middle or the beginning, in my experience, doesn't have any rational importance.
The reason why "new year resolutions" have acquired such a poor reputation is simply because most people want to change at the end of the year, and most people have poor self-control/intelligence so they end up failing. It's not because the New Year is an unlucky period.
Often, people also fail because their goals were unrealistic. You should start small. Not fapping, for instance, is a goal that can be realistically achieved by a low-energy incel.
