Under normal circumstances, most people will choose applied mathematics, and they have a good job and can afford to go to graduate school. For example, I am now studying for a master's degree in computer science, and I don't need to consider much about my work. In addition to computers, finance and statistics are all good choices, and they all belong to the category of applied mathematics. In other words, the direction of applied mathematics is the application of mathematics, while basic mathematics is obviously biased towards theoretical research and project establishment, and basic mathematics is still difficult to do. To enjoy good development, you must have perseverance and enough perseverance, unless your intelligence is lost to others. There is another sentence that our teacher said: In the first 35 years of your life, you will be extremely poor. As for the latter, it's hard to say. If you think you like basic mathematics, you can survive poverty when you are young.
