Be happy for this moment. This moment is your life.
The real trick here isn't the cheerfulness—it's Khayyam's insistence that your life *isn't* some grand narrative you're building toward, but rather the sum of discrete nows you're actually living through. We spend so much energy fretting over whether we're on the right trajectory that we miss the strange fact that the trajectory *is made of moments like this one*, unglamorous and fleeting as they are. When you're stuck in traffic fuming about being late, or listening to someone speak when you'd rather be elsewhere, that impatience doesn't exist outside your life—it *is* your life happening. The wisdom, then, isn't to force happiness into every moment, but to recognize that this very moment, whatever its texture, is the only place you actually exist.
