Overthinking the future is no different from restraining your present self.

Before words are spoken, the ending has been replayed a thousand and one times.
Before the body moves, in your mind you’ve crossed ten thousand mountains.
Before things are accomplished, the illusion of suffering still won’t let your troubles lift.
When everything is done, the past still continues to play out in your head.
Don’t think that there are endless matters beyond yourself.
And make the most of your finite cups in life.
