Yes, it's fine.
For some reason, this popped into my mind, from "The Rubaiyat of Omar Khayyam," translated/paraphrased by Edward FitzGerald:
Ah, make the most of what we yet may spend,
Before we too into the Dust descend;
Dust into Dust, and under Dust to lie
Sans Wine, sans Song, sans Singer, and--sans End!
And, with regard to "using our time," the "Jack London Credo" is not found in Jack London's writings, but was attributed to him by a biographer, and at least one scholar thinks it is probably authentic:
I would rather be ashes than dust!
I would rather that my spark should burn out
in a brilliant blaze than it should be stifled by dry-rot.
I would rather be a superb meteor, every atom
of me in magnificent glow, than a sleepy and permanent planet.
The function of man is to live, not to exist.
I shall not waste my days trying to prolong them.
I shall use my time.
