Actually, learning math is very interesting. But you can think of it as a game and a hobby. If it's just a game hobby, it can't affect your normal work and life, so you should "play" math while working.

If you want to study and work in the future, you need to take some academic degree certificates, and these certificates should not only be good at mathematics, but also Chinese, English, politics and so on. As long as you work very hard, you may get it later. But even if you get these certificates, you may not be able to find a good job, because there are too many people with high education now. Your self-taught certificate has no advantage. Mathematics is profound, and the deeper it goes, the harder it is to learn!

If you really want to take math as a career, you can study while working. When you have learned a certain degree, you can be a math tutor for primary and junior high school students, or go to some math training institutions in primary and junior high schools to study and practice. Turn math you love into a career!
