Better intuition requires deliberate thinking
Intuition is romanticized, as if all thinking is too controlling, and all the answers we need are simply waiting inside us. I think this is wrong. I mean, of course, intuition could be the secret sauce, if it’s well-trained. Your intuition lets you think and do without thinking; this covers gut decisions, but also fears, procrastinations, biases, etc.
So how do you train it? (1) Practice, repetition, mantras; (2) Metacognition: the ability to know when reason or intuition serves/betrays you; (3) Journal analysis: dumping thoughts is the beginning of the process, but I don’t believe getting it out is enough. The point is to look at your feelings and make sense of them.
What these 3 have in common is that they all require thought. By analyzing and running experiments on yourself, you train your intuition so that you don’t have to think in the moment.
If you want better intuition (a state of non-thinking), you will have to first do a lot of hard, deliberate thinking.
