If life happens and you miss a week or two and you know in your heart of hearts you're doing everything you can do just to tread water due to Life Happening, that's fine too. This requires radical self honesty. Are you really treading water or are you being a lazy slag? Only you know the answer to that. But the point is for you to get as much out of this as possible.
I know it's human nature to get intimidated and competitive with other people's goals, Lordess knows I'm guilty of that too. But if it's not driving you to be a more awesome you and instead is making you eat your stomach from the inside out with misery and perhaps shame, remind yourself that everyone is a special unique snowflake with special unique snowflake goals and life circumstances. The goal is for you to improve your life by hook and crook and bell and book. What is challenging for you may be a breeze for someone and what's a breeze for you may be challenging for someone else.
If you don't get a chance to do the first prompt until next week or three weeks from now, don't feel like you can't do it. You can always add your input to the page, people are still trickling in. It's not like I gave you a ten minute meditation to do to start, I asked you to hit the floor running. This may take a few days to do.
I encourage you to check out other people's responses to the first prompt to get an idea of where everyone is coming from. If you aren't able to participate in the experiment for whatever reason, you could still fill a very important role by encouraging your fellow Charmers in their transformation.
