“I can only be my own present vision of myself.”
It is a simple proposition to recognize that many of us spend time, either in the past or in anticipating the future, striving to be who we are not.
If we gave ourselves one task today, it could be to repeat to ourselves: I am my own present vision.
We can then avoid wasting our moments of today on issues of the past, as far as I know, there is no easy way to recover or change the past.
As for the future, contemplating it too deeply and with anxiety only wastes the gift of the moment, which is the only true time we can live within.
