the day is short, and the work is much; my goal is still a long way off
Proverb expressing that time is running out while the task ahead remains large; often used to convey a sense of urgency or the difficulty of achieving one's goals.
日暮れて道遠しというが、まだやるべきことが山ほどある。
As the proverb goes, 'the day is short and the road is long'—I still have a mountain of things to do.
Derived from the Classical Chinese phrase 日暮途遠 in 『史記』, describing one whose day is ending while the road ahead remains long.
