Just as Peter Drucker said, the best way to know the future is to build it. Because a person only knows what they see, hear, or do. Without these, only God Almighty can know. What a person knows without these is as accurate as what a fortune teller knows. When a person builds their future, they know it for what they have created. A person knows what they have done; this is the best way. So Peter Drucker is right, the unknown always leads to a question mark. An unknown path is like walking in the direction the wind blows; anything can happen. It’s like living life as it comes, good or bad, exciting and risky. On the other hand, if you build your future step by step, if you create a future entirely with your own decisions, if you follow your own path, it will be safer. The risk will decrease. It might be exciting, but it’s a safer path. If you continue in a distant direction, things can become much easier. But otherwise, you will miss many opportunities by living life as it comes. Opportunities will slip away. Perhaps it’s because they didn’t take advantage of them. But otherwise, the opportunities that will come your way will be fewer. Because you can say that you are working on a certain path. Knowing the future makes you feel safe. This is always an advantage for you. You know the future, you feel free. You can say this will happen, that will happen. But unlike the other approach, you don’t encounter uncertainties and indecisiveness. If you’re going to say one at that moment, you say one. Even if two seems more reasonable, you might be forced to say one because you chose one. Here, you know the future, you’ll say one. But since you’ve already built your future, you’ve built it towards one. Deviating from that path to two means leaving that path. One is more free, the other completely restricts your freedom. This means both are disadvantageous. But both have advantages. As for what Peter Drucker said, yes, knowing the future is building it. This can often be to your advantage. But living freely and developing completely without a plan is something else entirely. But when it comes to knowing the future, the best, even the only, way to know the future is to build it.
