Why does The Kin Project work?
The Kin Project works because it's designed to make change as easy as possible.
Each of the monthly challenges adheres to the following tenets of "easy change"...
1. Focus on one habit at a time.
It might be counter-intuitive, but, as James Clear says, "the best way to change your entire life is by not changing your entire life."
The Kin Project asks you to focus for one month on one specific habit that will improve the world (and your life).
It might take way longer than a month for the new habit to stick. That doesn't matter - the habits are supposed to be forever. Whether it takes you 30 days or 330 days to make it a habit, you'll get there eventually.
When it's time to start the next challenge, switch the focus to the new habit, but keep the previous one going. Keep repeating the process... and ta daaaa, we've saved the world...
