There’s nothing wrong with having a hobby, but if you want to call it a business, you have to make money

"If you’re not sure where to spend your business development time, spend 50 percent on creating and 50 percent on connecting. The most powerful channel for getting the word out usually starts with people you already know. If you build it, they might come … but you’ll probably need to let them know what you’ve built and how to get there. When you’re first getting started, say yes to every reasonable request. Become more selective (consider the “hell yeah” test) as you become more established. Use the One-Page Promotion Plan to maintain a regular schedule of connecting with people as you also spend time building other parts of your business."

One of the things "you need"  to do is remember you actually need  to make money. "This may sound simple, but busy entrepreneurs can easily become overwhelmed with all kinds of projects and tasks that have nothing to do with making money. Putting the focus on income and cash flow—measuring everything else against those standards—ensures that a business remains healthy.

Remember that the goal of business is profit. It’s not being liked, or having a huge social media presence, or having amazing products that nobody buys. It is not having a beautiful website, or perfectly crafted email newsletters, or an incredibly popular blog. In larger businesses, this is called accountability to shareholders. Business is not a popularity contest. The CEO doesn’t get away with saying, “But look at all these people who like us on Facebook!” Shareholders will not accept that. You are the majority shareholder in your business, and you have to protect your investment. You have to make sure that your recurring activities are as directly tied to making money as possible. There’s nothing wrong with having a hobby, but if you want to call it a business, you have to make money."
