Optimization: Adjusting something to reach its best state for a specific purpose. We often think that the fastest and strongest options are the best. The fastest way down a slope isn’t a straight line, but a parabola that naturally connects high and low points. A sniper can cause more lethal wounds at 400 meters than at 200 meters. Although the bullet travels faster at 200 meters, the wound size isn’t as large, and at 400 meters, the slower-moving bullet over a longer distance causes more friction as it passes through the wound, resulting in more severe injuries. In every situation, there is an optimal choice suited to the goal. Trial and error are useful for finding this optimization. - Joseph’s “just my thoughts”
We don’t care about money deposited in the bank. If we ask the bank for money, I believe they will certainly return my funds. However, as shown by Lehman Brothers ’ bankruptcy during the 2008 financial crisis , banks cannot guarantee 100% of depositors’ money. In South Korea, according to the Depositor Protection Act , only 100 million won (about USD 71,000 ) is protected, including principal and interest per person. Anything beyond that is actually at risk. In other words, money deposited in the bank is vulnerable to losing the principal. Investing means willingly accepting the risk of losing the principal while seeking profit. Whether we like it or not, we are always investing in our daily lives. Just because a risk doesn’t materialize doesn’t mean it’s gone. - Joseph’s “just my thoughts”
