Oftentimes personal development seems like a nebulous task. Since a lot of it takes place in our heads and hearts, it would seem that attempts at self-improvement are hard to quantify. However, could there be a way to use physical world productivity systems to produce inner growth?

On his YouTube channel, Tiago Forte recently explored using the Theory of Constraints to improve personal productivity and development. For those not familiar with the theory, it was developed decades ago to better understand how large-scale systems, especially factories, could function more effectively. A key focus of the process is identifying the bottleneck. The website Lean Production defines it this way:

The core concept of the Theory of Constraints is that every process has a single constraint and that total process throughput can only be improved when the constraint is improved. A very important corollary to this is that spending time optimizing non-constraints will not provide significant benefits; only improvements to the constraint will further the goal (achieving more profit).

Thus, TOC seeks to provide precise and sustained focus on improving the current constraint until it no longer limits throughput, at which point the focus moves to the next constraint. The underlying power of TOC flows from its ability to generate a tremendously strong focus towards a single goal (profit) and to removing the principal impediment (the constraint) to achieving more of that goal. In fact, Goldratt considers focus to be the essence of TOC.

Tiago believes that this theory can be applied to personal growth. In the video, he gives an example of how he uses it to improve his deep-thinking time for writing his next book. Since there is no physical bottleneck, what he explores is how his personal energy is the obstacle to his process. He then identifies ways to overcome it, such as blocking out time in the morning, exercising, eating healthy, and minimizing distractions. All these actions are ways to expand his capacity to think deeper.

The video is only five minutes long and easy to understand. I invite you to watch it and learn how the Theory of Constraints could improve your life.
