This is one of the biggest truisms out there that no one pays attention. I read this book by a guy called Keith ferrazi. The book is called "never eat alone" and the author himself is a master networker. When he was asked the secret behind his networking skills he said one word - generosity.
I've heard of that book. I have yet to read it, though. Thanks for mentioning it!
I agree that there are a lot of truisms that people don't pay attention to. It's sad that they'd choose to be lied to than hear even the most uncomfortable truths.
Cheers!
