Everyone's intelligence and knowledge, outlook on life and values, how they behave and treat others are all different. A large part of the reason is that they have different levels of education and richness of knowledge. Even if you are talented and intelligent, you will accomplish nothing if you are lazy in learning. On the contrary, even if you are born dull, you can achieve success if you study hard. We must be keen on learning, and we must be good at learning. We must not stick to the rules and imitate others. Everyone should reflect frequently, sum up experience, and explore learning methods that suit them.
