its always difficult to find something i like though, my criteria is: no school/robots/sports/fantasy/space/hitler
and yes, kanji are crucial unfortunately...
usually asians study japanese and a skill at the same time, while westerners only study one of them... no idea why that is... since the day i moved here i didnt have any day withoit having to know intermediate to advanced japanese... of course there are enough people who dont need that, i am very envious... but i wasnt that lucky, otherwise i wouldnt have gotten a flat/job/etc...
a former assistant of my former boss studied something abroad and she studied english before she moved until she was good enough to get by and then studied at night, working/studying full time during the day... and that is no exception, especially among artisans, who study continuously... my boss(es) did not only expect the same from me, to them any other way was unthinkable... so naturally i had to advance my skill set and the language (and i was already quite okay at speaking japanese back then)... and that boss had me working way past midnight, straight after i returned from school (visa reason), nearly every day...
fortunately i was used studying a lot in my leisure time...
i still study every day, though often its just reading, while working about 80 hours a week (usually only one day off)... as said assistant said: "i just slept less"...
that is more or less normal for creative people here who dont work in front of a screen... you work and improve you skill in your leisure time... since i also got to improve my japanese, i got a little bit more to do...
as for studying in the wild, i do approve that and any other form of passive learning, once youre good enough to do that... years ago there have been a lot of things i thought i understood, only to find out that i hadnt a long time later... i hear/read similar mistakes from other people... how often is the past tense not used to show the past, for example...
another good thing about that is that there are a lot of words that you cant find in dictionairies unless they are very specialised and those are japanese to japanese dictionairies usually...
of course no one has to choose my way of doing that... among japanese it is not uncommon, though (leave out the slacker generation^^)
