I share with you a method, this method is from the East, it is very simple and I use it often. When you decide to do something, no matter what it is, travel, go to school, work, find someone, run for president, take a plane, etc. As long as you decide to do it can be predicted. When you start doing this, your intuition will use the good or bad of a small thing to predict the success or failure of the thing you are trying to do. For example, I was going to withdraw money today, and after I went out I saw a dog urinating on my shoes, which made me feel really bad. This means that you will have trouble getting your money out, or you won't get it at all. The frequency of small things will directly affect the success or failure of big things, which is called the butterfly effect. The butterfly effect can be a thing, or hearing a word. In short, if you have a bad feeling, things will fail, if you have a good feeling, things will be done very smoothly.
