research from Stanford professor Kelly McGonigal has shown that the number one reason why willpower fades and people fail to remain consistent with their habits and goals is that they don't have plan for failure.

In other words, it’s really easy to confuse being consistent with being perfect. And that is a problem because there is no safety margin for errors, mistakes, and emergencies. (You know, the type of things that make you a normal human being.)

But if you want to maintain your sanity, reduce stress, and increase your odds of long-term success, then you need to plan for failure as well as focus on consistency.

Cutting yourself some slack becomes even more important when we consider the science behind habit formation and continual improvement. Research shows that, regardless of the habit that you are working to build, missing a single day has no measurable impact on your long-term success.

It’s never my intention to make a mistake, but if I do, I have given myself permission to view my progress over a longer timeline than a single day or an individual event.

Planning to fail doesn’t mean that you expect to fail, but rather than you know what you will do and how you will get back on track when things don’t work out. If you’re focused on being perfect, then you’re caught in an all-or-nothing trap.

In other words, it is all about average speed, not maximum speed. Daily failures are like red lights during a road trip. When you’re driving a car, you’ll come to a red light every now and then. But if you maintain a good average speed, you’ll always make it to your destination despite the stops and delays along the way.

I find this to be an empowering way to think about consistency and progress in nearly any area. It’s never my intention to make a mistake, but if I do, I have given myself permission to view my progress over a longer timeline than a single day or an individual event.
