“Eventually, you’ll learn to focus on the present and let the past go.” He guided us down a side street I knew well. “Reliving what could have been but never will be is pointless. It’ll only hold you back from what you are. One of the hardest things anyone can do is live in the here and now. Not worry about the future, not rehash the past. Be present, that’s the secret to changing your future. To finding true happiness.”
