One thing is undeniable: we have a chance to learn and grow every day, no matter what we did not do yesterday or neglected to do last week. The only moment, the only life we have is in the NOW. What happened a few moments or several years ago is gone, what will happen this evening, or next month when we go on holidays is not here yet. Thus, if we live our lives thinking about past events or future possibilities, we are literally not living our life.
