The only moment that we have control over is our present, this right here is the time that you hold power over. It's you who decide how you choose to spend it. But sadly we all live in the present but our minds are either grieving over the past or worrying about the future. And due to this worry, we fail to enjoy what we already have, our present. One should understand that only our present is something that is certain, unlike it there is no such certainty about the future and there is no part of our past that we can change. We should stop living in the moments that we have no control over. Just because we don't understand the importance of what we have, we are not able to make the most of it and we let our minds wander in the past and the future.
You should allow our minds to explore what you have in the moment so that your mind is occupied with the thoughts of the present so that there is nothing else for it to worry about. One must treasure what he has rather than worrying about the future that is not even guaranteed. And if any tragedy has struck you, mourn for it when it has happened, don't carry it with you to destroy the life ahead of you.
Make full use of the time that you have with you right now. Don't burden yourself with the worries of the future, no one knows if they'll get to see another day and don't make yourself suffer over your past, because by thinking about it you only make yourself suffer twice. Embrace the moment you still have, enjoy it to the most. You won't get it again. You cannot change what has already happened, but there is one thing that you can do and that is to make more good memories while you still can. So that when you look back, you have enough good memories that you don't have time to think of the bad ones. Life is too short for that. If we keep stressing our minds over the things that are in no control of us, we would not be able to control the things that we can. Don't take this life for granted. Not everyone is blessed with the things that you have. Keep enjoying every moment of it and keep thanking your Lord for giving it to you.
Don't go too fast or don't go too slow, go with the flow as you enjoy every moment of your life. Feel the moment that you have right now, spend time with the people close to you while you still have them. Don't stress your mind, let it explore and expand. Concentrate on your present and live it to the fullest.
