How do you know that you are suitable to learn Feng Shui?

This seems to have nothing to do with birthdays, right? This is mainly people's understanding, interest and learning ability, feng shui and so on. Mainly rely on your own understanding and endorsement of the knowledge in this book, otherwise how can it be applied to life? Because of your interest, if you don't like it and force yourself to learn, you won't achieve anything. So interest is also very important. 、
