How many business cards might you collect at a networking function? Five, ten, twenty or more?
You might get back to the office a couple of days later and sort through the cards, deciding how to follow up on each one. With many conversations in a short space of time, and maybe a few days in between, you may struggle to remember key points of relevance for the follow up.
Most business cards have lots of blank space. Use it. After each conversation pause for a moment and make a note on the card of where you met the person, the key points of relevance and what follow up is required.
