The plan will go sideways.
You will be called to an impromptu meeting.
The priorities will change
You will need to redo it.
The computer will crash.
You won’t have it backed up.
You will turn up when you didn’t need to.
The room wasn’t ready.
You have run out of it.
The person you are meeting didn’t show.
You ordered way too much.
The technology won’t work.
So, it happened.
There is nothing you can do.
Now how are you going to get back on track?
