I think you're fine if you only have 60 listings! I just made it past 70, which is really exciting! I've heard that 60, 100, 150, and other numbers are the "special" numbers at which you get better sales. I think the more listings you have the better you have a chance at getting views, because you have more things for people to look up and find you... keep creating! List as much as you can afford to list, and promote on teams, Facebook, and wherever else you have the opportunity!
