If you’re reading this, you take your skills for granted. When you see that people who do similar things to you do well and a much larger group of people who do not do those things fail, you’ll realize your system works and there are other (inferior) methods that you’re choosing not to use. This means you have control. Control means not-luck.
You have a system (if you take the time to notice it) and it works. You’ll probably see what they do is pretty similar to what you do. You both get good results and you’re peers. It’s not luck.
