… received a thank you gift in the mail.

It was from a colleague who thanked me for introducing her to another colleague who ended up becoming her client.

A few things worth noticing:

• People never tire of being thanked.
• Physical stuff (e.g., snail mail) has more impact than electronic.
• Gifts are more appreciated than just cash (even if the value is less).
• Unexpected gifts are appreciated most of all.
