Everyone you ever met and knew in your life will eventually die. All of the things you had eventually will break or wear down after you are gone. Even a statue degrades and erodes to the wind, sand and water. There will eventually no trace of your existence on this planet and to really send it all home to you, eventually when the sun turns into a red giant it will consume the earth wiping out all of human history or anything you might have “left behind.”
Just enjoy the ride folks. We are here for a limited time. Try not to stress, do things you love and try not to be a dick to others in the process. You only get one chance to do this and today is the best day to start doing it right.
