If you don’t know the word, get acquainted with it. More or less, it means that your understanding of the universe is that you carve your own fate. The world isn’t happening to you (fatalism or determinism). You are crafting it however you see fit. When you find yourself complaining about how you aren’t successful because of some outward variable, you aren’t in a state of efficacy. And good luck, because luck is all you’re counting on. Instead, when you start looking for ways that you personally can change the landscape, that’s how you choose your destiny. And that destiny is whatever you want within your control. So take control.
