That thing, that task, is not going away.
The deadline is approaching.
It cannot be deferred.
Everything else will have to wait.
Later has become now.
It can no longer be avoided.
No longer put off.
It has been postponed enough.
It cannot be ignored anymore.
There can be no more distractions.
Time’s up.
No more procrastination.
There’s no more time to do so.
“You may delay, but time will not.” – Benjamin Franklin
