Ah, the value of the lowly 3x5 card.
1. For writing down a good idea that springs to mind.
Not written down, such ideas usually disappear.
"Words are birds" and quickly fly away unless captured.
I use this old-fashioned method a lot. I've got cards on
my bed-stand, in my pocket, and in my car. When I get a good idea while driving, I write down a few key words when stopped at a red light.
2. When at meetings and social gatherings, you'll often
meet someone who doesn't have business cards handy. You can use a 3x5 card to get their contact information.
An upscale alternative I use is a blank business card
I created that says "My Other Card" and then has
3 lines for Name, Email, and Telephone. (You can get
these for a pittance at VistaPrint.com.) When my new
friend says "I've run out of cards," I say, "No matter.
Here is your Other Card." This always gets a chuckle,
and many folks ask me for an extra card they can copy.
3. Not a card, but a method. 3 times each day at the
office, M-F, contact an acquaintance with a short phone
call, a handwritten note, an email message, or perhaps
mail a clipping you know will interest them. Your
"likeability quotient" will increase accordingly.
3x5. Simple. Easy. Low-cost. Communication magic!
