Learn as if you were to live forever

अजरामरवत्प्राज्ञो
विद्यामर्थञ्च चिन्तयेत् ।
गृहीत इव केशेषु
मृत्युना धर्ममाचरेत् ॥

- हितोपदेशः

A wise person should pursue knowledge and wealth as if he was to live young forever. He should practice moral principles as if death has grabbed him by his hair.

Learn as if you were to live forever.
Live as if you were to die tomorrow.
