I think the fundamental differences are mainly as follows:

1, kindergarten brings us innocence, natural happiness, and a simple principle of being a human being. In college, we learned more knowledge and principles of being a man.

2. Kindergarten can provide us with few opportunities to make friends (mainly few people), but when we go to college, we can make countless friends if you want.

I think this is the most important point: in kindergarten, we rely on the supervision of others (for most children), but in college, we have a lot of time to ourselves, so we can arrange our own time to study. And through the study in the university, we have opened our minds and gradually developed how to study, so that we can learn new things and new skills quickly in our posts. Therefore, it is easier to achieve success and handle interpersonal relationships.
