It's a simple enough question: how do you define productivity? For the Ridiculously Efficient, productivity is doing more work in less time. It's working effectively and efficiently, completing work tasks properly the first time in a time-conscious and resource-conscious fashion.
To really define productivity, though, you must dig a bit deeper into the concrete figures and statistics that define success or prowess in your areas of responsibility. A writer who churns out 20 articles a day might appear productive on paper, but if it took him 20 hours to write those articles, that statistic suddenly isn't as impressive.
Define your own productivity by evaluating all the different aspects of your day and deciding what you must do to be successful at each. Then, use this example of peak productivity as a road map for your day. To supercharge your productivity even further, use this road map with the Track, Hack and Attack method.
