Remember your past ,dream for your future but live in the present.

There is the past, and there is the future. The present is never more than the single second dividing one from the other. We live poised on that second as it's hurtling forward—toward what?

The past was gone and the future had yet to unfold, and he knew he should focus his life on the present…yet his day-to-day existence suddenly struck him as endless and unbearable.

There's no future in spending our present worrying about our past.

The Present weighs up the Past envisaging the Future

The past is fixed, the future doesn't exist, and the present is ever changing.
