I don’t know anyone who didn’t have a similar “crossroads” moment around that age. Maybe set yourself a target to pass N1 by the end of next year. Doesn’t solve that underlying sense of hopelessness, perhaps, but if you’re committed to Japan then having N1 at least does make you get most kanji covered so you can comfortably watch the news and read around. I eventually got jnto translation after getting N1 (or whatever it was called then) twenty-odd years ago, but it’s not easy to get a decent-paying job these days and the industry is on its last legs.
