Yesterday is history, tomorrow is a mystery. Today is a gift of God, which is why we call it the present. Each day is a valuable gift of time that should not be squandered or wasted because time is something that you can't take back or save up. We are all born with a set amount of time to be on this earth, and you never know when your time here will end. There is no counter or deadline that tells us when we will move on to the next life, inspiring us to make the most of the life that we have left. Every day that you wake, even every breath that you take, is a gift that god has given you. You can not change the past or predict the future, but you can live in the present and be grateful for the opportunity that you have through the grace of god.
Don't waste the precious gift of today, live in the present and make the most out of every second. Dwelling in the past will not get you anywhere, and focusing solely on the future means that you are not enjoying the present that you are currently in. You were blessed with today for a reason so make sure that you take advantage of this gift and make full use of it. At some point these gifts of time that god gives us will end. When that happens make sure that you have said and done everything that you want to say or do in this life.
