The best gift you can give is one about them
If you sent a card that had 12 business building ideas — one a month — or the 12 business building days of Christmas, and offered to spend an hour a month with each customer to help them expand on the idea and implement the idea, THAT would be a gift. Certainly ten million times better than your foil stamped card that’s in the trash December 26th, or sooner.
Only one problem with this gift: It requires WORK!
But it will build solid relationships and earn you the respect you deserve.
