Find pattern in your favorite things. I didn’t acknowledge the strength of collecting stuff people like. I have been collected stamps when I was kid. However, it was homework from school, not on my own initiative.
Now I know why collecting stuff is important. It is related to creativity. Creative can be found from pattern. If you collect images you like, you can find your own pattern from your taste. It helps you find your specific preference. It increases your metacognition. If you don’t know about yourself, you should start to collect something you like.
