Personally judging whether a person is suitable for learning mathematics depends on whether ta is interested in and loves mathematics and is willing to make efforts for it. Even if I didn't continue to do academics in the end, the time spent studying and studying mathematics in recent years was not in vain, which must be a wonderful journey for ta's life. There are various types of mathematics itself, and mathematicians actually have various styles of learning mathematics. For example, partial analytical mathematics may require all kinds of "hard work", but some partial combination problems often require more imagination; Some mathematicians are good at solving difficult problems, while others are better at discovering the connections between different mathematical structures. For the same differential equation, pure numbers and applied mathematics may have different views. From this perspective, we should not conclude that we are not suitable for learning mathematics just because one of our indicators is not as good as others.
