If you knew something you were already doing made you the most money, would you keep on doing it? I take time out on the 23rd of almost every month to look over my business as a whole and see where things are working and not working. I call it my Business Development Day (or Biz Dev Day for short).
On a recent Biz Dev Day, I wrote down all my clients names and next to each how I had gotten them. It was a really useful exercise because it told me that I had gotten almost every one of them by networking! In other words, word-of-mouth. People who I had met through going out to networking groups or ran into while getting coffee had all remembered me when they needed graphic design or knew someone who did.
So, if you are going downtown to get your morning coffee anyway, think of it as a networking opportunity because you never know who you might meet that will refer you or hire you themselves. Keep it up and it may become the key to growing your business!
