Sublime's marketing headline "Live on purpose, or miss it" works well for these reasons:

• Creates urgency with the stark choice between purposeful living or missing out

• "Live on purpose" suggests intentional, mindful existence rather than drifting through life

• "Or miss it" implies that life's value is at stake which raises the emotional stakes

• Appeals to people feeling unfulfilled or seeking more meaning in their daily lives

• Simple language delivers a profound philosophical concept

• Creates a sense of FOMO on life's deeper meaning (FOMO sells)

• The brevity matches the urgency of the message… there's no time to waste
