Japanese uses three writing systems at once. Hard things get learned anyway, one character at a time.

Difficulty does not stop people, it only lengthens the schedule. A system that looks impossible from outside gets learned by people who never tried to swallow it whole, just the next character, then the one after that. Scale is the illusion; the unit of work is always small.

Take whatever looks enormous to you right now and find its unit. One formula, one verb, one page. Do that unit today and refuse to estimate how many are left.
