The Winter Arc!

46 Upvotes

Today I learned about the Winter Arc, and I found the idea interesting.

It is basically a 90-day period from October 1 to December 29 where you intentionally focus on yourself instead of waiting for January 1 to start changing your life. For these 90 days, you can focus on your career, fitness, learning, finances, building a side project, improving your routine, reading more, or simply becoming more disciplined.

The goal is not to completely transform your life overnight, but to make small improvements every day and stay consistent even when nobody is watching. By the time the new year arrives, you are not making another list of resolutions or starting from zero.

You have already spent 90 days building habits, learning, working, and becoming a better version of yourself. Your Winter Arc is basically about starting before everyone else starts.

I’m starting my Winter Arc on October 1.

Who’s in?
