Most people live in their past or future.Every great person or motivation books teaches us one thing, that whatever it is, is just today, so one must learn to live in the present. Many people also try to live in their present and if seen, we try to make it better by only work on our present.
Yet if we look in a little deep, then we will find that more than half of the world is living either in its past or in its future. Some people always think about their past things, whether they are good or bad and some are lost in future dreams. The effect of this is that people do not focus as much on the work they are doing in the present as they should and then even after a day today will become a part of our past.
Life becomes past like this slowly, and then we cannot change the past, so focus on today as much as possible, the future will be good on its own.
