Live as if you were to die tomorrow. Learn as if you were to live forever.
—Mahatma Gandhi, Goodreads citation (did not find any authoritative source of this quote)
This used to be my motto for a long time before college, cannot recall when this disappeared from my active conscience. Caught my eye when Prof. Adam Porter quoted this in the announcement email for week 7 of his Coursera class on Programming Mobile Applications for Android Handheld Systems. (BTW, this is the max I have come so far with any of my attempts to learn Android programming. I recommend this course but some familiarity with Java is required.)
