Okay, this one is mainly for the college students. You need to do this. In college, get close to a few of your professors. Chat with them, offer to eat lunch at the commons hall with them. Eventually, ask them to come by your house to eat dinner (make sure you are of the same sex!), and invite them out to a pub for a beer. This may seem weird, but there is reason by this. Later on in life, you are gonna need these references for a job. And voila! You have networking gold because you did this! Trust me, this is a great way to help yourself later in life, so start on it now!
