“If the past or the future existed some scientist would have discovered it by now” Eckhart Tolle.
You cannot live in the past or the future, they do not exist . The only moment you have is this one.
You spent your entire adolescent being programmed to look in the future or work through the past but no one ever tells you how to actually live your REAL life. Real life as in the one you are in right now. Its amazing we literally live in the eternal now!
