Every day you wake up is day one of the rest of your life.
Your choices today affect everything that follows. You are free from past obligations, decisions, mistakes, and successes because it's day one again. Today could be the beginning of a new company, a new project, or a new relationship.
Today could be day one if you make it so. And that's what you should do: treat every day as day one of the rest of your life. See it as a new beginning, a fresh start, a reset. Live more intentionally with the limited days you have.
