Is your life the most important thing in this world for you?

Do you often feel like a hermit crab, who constantly worries about seizing the day, taking advantage of a perfect opportunity, clawing underneath oneself all the things one comes across. Because if I think that my life is the most important while you think that your life is way more important than mine, then where is the ultimate truth, who is right, so to speak. We see a discrepancy, and the answer does not lie in relative points of view, it is something more profound, explain what you honestly think.
