Everyday we have on this earth is a gift.Like any gift we are given, we have to show appreciation and give thanks for that gift.My personal beliefe is that it is a gift from God, so I give thanks for it, but no matter your belief, you can give thanks just by being great and doing the best you can do. Yesterday is gone, tomorrow is the future, but today is the present for which we have to be thankful.
Have a great day.
