If tomorrow is never promised

Why is it so difficult to live for today? The nerves when you're drinking coffee thinking of to-do lists for the week; frustrations when someone accidentally inconveniences you; the goals that seem so far-reached and keep growing no matter how close you get. Yet, there's the wind that reminds you of today; the sun and the birds; a phone call from a loved one. And the closer you can get to enjoying that, the better your past, present, and future really are.
