Has it ever crossed your mind that whether you’re thinking of the past, or imagining your future, you can only do them in the present?
The past you can’t change, and the future can’t be fast-forwarded.
So, dwelling on both the past and future is really a waste of time. And guess what?
There’s no future if you screw up your present.
So, please. Do what you’re supposed to do in the present and the future will come to pass (no pun intended).
