Daily Chinese Proverb: Working Hard

This proverb suits my past week, it is often used to describe someone who has worked extremely hard. Recently I have taken on more projects than my watch can handle, (at least whilst keeping up with my unpaid jollys) and if I could stop time to finish and spend all the time I want to on each thing, I would love to.
