Dream as if you'll live forever. Live as if you'll die today.

Two clocks run at once in this saying: one with endless time, one with only a single day. Dreaming as if you'll live forever means letting your ambitions be large and patient, free from the fear that it's too late or too big. Living as if you'll die today means refusing to postpone love, honesty and attention to some better moment. Together they ask you to aim far while staying fully present.

The idea echoes old traditions: the Roman carpe diem and the Stoic habit of remembering mortality, both meant to make life clearer rather than gloomier. It also fits the image of James Dean, the actor who died in a car crash at twenty-four and became a symbol of intense, unhurried-by-caution living. Still, the attribution is uncertain, since the line is widely credited to him without a clear source.

In practice, imagine someone who has always wanted to write a book. The "forever" side lets them commit to a long project, a few pages each week, without demanding quick success. The "today" side nudges them to call a friend they've been neglecting, instead of saving that for later.
