dō ni isogashiki wa wakaranai ga, asita waやすみ na no de dō ni jikan o yūka ni tsukau ka o kangaeru

I don't know how busy I'll be tomorrow, but since I'm off tomorrow, I'll think about how to use my time effectively.

dō ni jōzuiku ka wakaranai ga, dō ni dōryoku suru ka ga taiせつ da

It's unclear how things will go, but how much effort I put in is what matters.

dō ni muzukashii ka wakaranai ga, dō ni tokku ka o kangaeru koto ga taiせつ da

It's unclear how difficult it is, but how to solve it is what's important.
