LinkedIn has been a great source of referrals for me. I have been able to maintain many friendships using this service. One of the most surprising is that sometimes you get endorsements from people who you don’t expect.
I had someone endorse me that I didn’t expect. When I knew him he was friendly but I didn’t ever have the thought that I was anything other than someone I helped. Often when people like you, they make it obvious with compliments, gifts or so on. So it is always a compliment when someone not only remembers you, but also surprises you with an endorsement.
We sometimes impress others the most when we are just who we are.
