The sun and Earth are nearly 5 billion years old and estimated to live for another 4. Humans have been on Earth for 100,000 years. If Earth is a year old, humanity has taken almost 2 seconds of its life. Your lifespan is even more minuscule. Seeing the big pictures simply burns away the worries and lets you focus on what you actually care about, what brings you pleasure and purpose. A day that begins with a genuine gratitude is never wasted.
