Anybody can send away to city hall for a business license, but you never feel like you are your own company until you have to go on the road for it.
There is no sales team to gather orders. You can’t depend on your website’s contact form to gather leads. You know that an ad in the local paper can’t pay for itself.
There is just you, yourself, numero uno, picking up those business cards, establishing that rapport, and making those connections. The people you meet might be your friends for decades to come. Meeting people in the flesh says that you are willing to put in the time and effort to solve your customers problem. You are present and at their service. It might be all you have right now, but it also might be all you need.
