Want to build a habit, but you just feel it will be too hard? Good news! According to DoC it takes 21 days to build a habit. Here’s what she found.
Becoming Undead Takes Some Getting Used To
When DoC first started reviving people that she… uh… acquired…

… she found that if the newly alert zombies ever “dozed off”, they would start screaming when they once again became conscious. This would continue for exactly 3 weeks. At that time, the zombies became used to their situation, and it just became normal.
This made DoC think — first about a serum she developed to wipe her patients mind before revival — but secondly about what this meant for habits. After some experimentation and research she found this magic number 21 kept showing up, not only in her experiments, but in many experiments in your world as well. It seems some doctor at some point in your history found out the same thing.
So what does this mean? It means it takes 21 days to build a habit, but there’s also more to it.
How to Build a Habit
In order to build a habit you have to do it every day. It has to be something you do no matter what. The key is that it’s not how much you do it, but that you do it each day. It has to become part of your existence.
It seems unnatural at first, but after 21 days it’s normal. It’s part of your routine. Now that doesn’t mean that it’s “locked in” and it will never go away, but it does means it’s routine. To make it stick, you keep doing it. You make sure to size it right so it’s something you can do each day without fail. You can do this by following these simple steps:
- Use Your Habit Building Superpower: Use identity to enforce your habit. If you view yourself as a runner you will have an easier time trying to run.
- Use the Easy Streaking Fun™ Model: Make the activity easy to do so that you keep a streak of activity alive each day and make the activity fun.
- Believe in Yourself: You can do it! Believe in yourself and make it happen.
It takes 21 days to build a habit. Make today day 1.
