If a task is once begun

I've experienced that on more than one occasion. It's almost as bad as waking yourself up with your own snoring!

If you're wondering, the title for this comes from an old rhyme my mother taught me:
"If a task is once begun,
never leave it 'til it's done;
be it great or be it small
do it well or not at all."

Feel free to use that. Kids LOVE it!
