According to Eckhart Toole, “The present moment is all you ever have. There is never a time when your life is not “this moment”. The moment you become conscious of it, it’s over.
Thinking and reflecting about the past allows us to learn from our mistakes. Without dwelling on this, we would never develop into intelligent beings. The same idea is true about planning for the future. We wish the future to be promising, and the only way to achieve that in our busy schedule is to plan accordingly. This will relieve us from whatever is pressuring us and be in a better situation. Only you can live in the moment.
