First of all, it is necessary to acquire knowledge in various aspects and try to understand the world and reality from different perspective. Build own opinions gradually, but don’t exclude other information, and we can make our own choices rather than based on the opinions of others. Second, we should overcome our laziness, we can’t summarize everything, sometimes “draw inferences from three examples” is not better for broadening our horizon to understand the world, and knowledge is unlimited, we should understand the usefulness of education and receive information, rather than a shallow, what things only know a little. It is very important to learn to think independently. We need to learn to acquire knowledge and establish our own opinions, and to think and look objectively, so as to understand the essence and reality of things through thinking.
