Why is networking so important?  It keeps business opportunities in the pipeline.  Just because you are busy now, doesn't mean things might not slow down eventually.  Remember, winter is coming.  There will be a change in business.  You can network to generate new and increased referrals, which will lead to increased business.  You can network to gain new opportunities with other business owners.  Networking can lead to some great connections, both professionally and personally.  One of the best things about networking is that the more you do it, the easier it becomes.  Those once dreaded events turn into fun with old pals.  The stress will melt away and you can relax while making your way around.  

Try it out!  Attend a particular organization's events consistently for several weeks or months and notice how much easier it is.
