Education plays an important role in human's lives. It allows them to obtain a lot of information from different fields that are useful in their daily life. Some people believe it is better to have broad knowledge of many academic topics than specializing in a specific. Although they are both important and improve our life in some ways, I believe that it is key an expertise in a subject.
The first argument in favor is that it helps people to find a job. Nowadays, organizations are demanding for people with an important technical background. As a result, we need more knowledge of some specific areas in order to work at important companies and earn a good salary. Besides, somebody specialized in a particular subject has a high probability to get a job more easily.
In addition to having a deeper knowledge, students can also remember information easily. Besides, they can focus only on reading important information. As a consequence, they are more motivated when they are acquiring information of a single topic of their preference. For instance, a lawyer will want to study all the terminology related to his field. However, he will feel discouraged when studying Mathematics.
Finally, having a broad learning does not have the advantages on the efforts needed to be successful. As it was mentioned in the first paragraph, we need deeper understanding of a subject to get a highly paid job. Although with broad knowledge we can decide which subject is the favorite and more helpful, it is necessary to continue studying, but in a lower level of knowledge on it. Therefore, it requires more effort and time to be successful.
To conclude, having broad knowledge or specializing in a particular field are both important. However, specializing in a subject allows people to get a highly paid job with less efforts to be successful.
