Iteration and Optimization: It would be great to do something well on the first try, but humans are not perfect. To do it well, you need to go through repeated failures and successes, and during that process, you have to identify the pattern that works best for you. This process is called optimization. Optimization requires iteration. Efficiency and profits are guaranteed by repeating a process until a particular singularity is achieved, thereby maintaining that level of excellence. The general rule for success in society is to iterate and keep optimizing. Being consistent is the fastest way to improve. - Joseph’s “just my thoughts”
Even though a country's total population is decreasing, the economic situation could be improved by increasing the total economic activity of the remaining population after the decrease. Of course, there is a statistical population threshold below which this effect occurs. Nevertheless, this effect would not work in the case of a force majeure, such as a natural disaster or the outbreak of war, however, this assumption would be valid because a rapid population decline is a highly exceptional event that would not normally occur. Therefore, an increase in the economic activity of this population should be required during an economic recession. Applying this perspective, for building a solid relationship with your followers on Instagram, the number of followers is less important than the activity between them and you. This is called the "Engagement Rate (ER)". - Joseph’s “just my thoughts”
