Networking isn’t just about finding work.
When you're first getting started as a freelancer or business owner, it can be easy to see networking as just another way of finding work. But you're much better off going in with an open mind. A networking session might lead to a new project. It might not. But it will always lead to connections (unless you stand in the corner not interacting with anyone - in which case, are you just there for the coffee?).
It's always helpful to meet people further along in the process than you are. And nine times out of ten these are the people who are most generous with their time, because they remember what it was like to be brand new to being self-employed.
Networking is also a great way to meet new friends who understand the challenges (and benefits) of being a freelancer or business owner in a way that other friends and family might not. It's a chance to build mutually beneficial relationships, because you'll be able to bring different perspectives and expertise.
Building new connections and having a support network is important to anyone, but it's particularly important when (and this is true of a lot of business owners and self-employed people) you spend a lot of your time working alone.
But remember - you need to put time and effort into any friendship, and your relationships with business connections are no different. You'd (hopefully) not lose contact with a friend for months on end, only to reappear when you need a favour. So, treat the connections you make through networking with the respect you'd expect from your friends. That way, you're both more likely to get more out of the relationship.
