Increase Your Productivity with the OHIO Principle
The Only Handle It Once principle, otherwise known as OHIO, is a useful model that will help you improve your productivity. The idea behind it is that once you start working on a specific task, you work on it completely from beginning to end. That is, once you touch an activity, you do everything related to it until you finish.
This approach is especially useful for shorter tasks, like a quick email or phone call. Instead of letting it take up space in your inbox or to-do list, you take a few minutes to take care of it. The task doesn’t even ever have to make it to your to-do list. Of course, it is not always possible to do everything at the moment. If you cannot work on the incoming task immediately, set a reminder at that moment to work on it in the future.
