Using time wisely is wise living. Time passes and never returns. While living we're in time. We go beyond time through time by way of time. Facing time allows a glimpse of the timeless, the eternal.
Having "time on our hands" disturbs many people. Boredom sets in. Anything seems better than doing nothing or "just" being still.
Love is what we want. Free time is for love. Do and be what we love. Lovers of wisdom spend time engaged in philosophy - a word that really means "love of wisdom". Do what you love. Be what you love.
