How do you write a good luck note?

A card would be nice too. Inside the card you could put: If it's business or a coworker or someone you don't know well put: Jack Wishing you good luck on your future endeavors. If you are good friends then say: Jack Wishing you the very best of luck and I hope and you deserve the very best. Please keep in touch and let me know how you are doing.
