I think keeping busy is good if you are keeping your old clients and making new ones along the way. It is when you are not making new clients is when you have to worry in that you are not reaching out to those that don't know you as of yet. You need more exposure via some sort of media. Advertising works weather via facebook, linkedin, twitter, your own blog or by the old fashion way Newspapers. Your business has to grow to keep pace with your compeditors.
