For Want of a Nail

For want of a nail the shoe was lost.

For want of a shoe the horse was lost.

For want of a horse the rider was lost.

For want of a rider the battle was lost.

For want of a battle the kingdom was lost.

And all for the want of a horseshoe nail.

This is a very old proverb which goes to show us that for a small action it could have very large consequences. This proverb was used in the movie "Fast And The Furious: Tokyo Drift".
