Translation
How do I say "Stressful lately but I need to press on!" in koreanwill it be right to say 요즘 힘들지만 힘내야지 or is there another nice way to write it?
I think 요즘 힘들지만 힘내야지 is a fine translation.
힘들지만 means "difficulties" in general, so if you want to be more specific with "stressful", you might want to say something like 요즘 스트레스 (많이) 받지만 힘을 내야지.
