Unfortunately I did not study well at school, I was not interested in many things, and I did not understand that things.
But I have matured, interests have become more. I am now 20 years old. Now I have to correct the mistakes of the past. I am now studying, writing and earning money with JavaScript. But I want to study mathematics to understand more complicated things in computer science and learn other languages (English, Russian, Japanese).
And is it possible to study all these things (to study, write on modern frameworks, learn math from the beginning, and learn languages (not programming)) in parallel? For example, doing own work for 4 hours, after that to study mathematics for 3 hours and after that to learn languages 2 hours.
Will not I have a mess in my head? And how to learn things correctly so that there is no mess in my head?
