I don't need any outside help to get me ready.
He had decided that it was time for outside help.
He doesn't think they can do it without outside help.
The most important thing I'd say is don't wait too long to get outside help.

The only way it could be done was with outside help.
So if things begin to go wrong, they don't like to ask for outside help.
They would have to do what had to be done without outside help.
Without outside help it will take even longer to put things right.
