I recently came across an article on Entrepreneur.com that got me thinking. Here's an excerpt:

"Every time John Costigan of John Costigan Companies hands out one of his metal business cards with a custom cutout of his own profile, he's giving away $2. But Costigan, whose Cary, North Carolina sales training firm grows yearly, says it doesn't hold him back one second. He estimates that he's gained over $100,000 in business since debuting the cards in 2003. 'Metal represents what my company is - sharp, different, bold,' says Costigan, 43. He hands out a card to every person who takes his class, reasoning, 'The return on investment is more than worth it.'"

What an interesting idea - a subtle marketing message built into your business card. There are so many ways to make yourself memorable - whether with your business card, a thank you note, or simply the way you treat customers.

What are you doing to be memorable?
