Networking and selling do not mix. . . especially at the same networking event!
Someone once said, “Networking and selling are like oil and water. They both belong in your financial engine, but you must put them in separate containers.” Don’t know who said that, but they were very wise! You come across as self-serving and that’s not the way to network.
Tooting your own horn is the worst thing you can do in a social situation. Nobody but nobody likes to have services crammed down their throats.
