Successful freelancers are independent and adaptable. We know how to get things done without the "amenities" available to the traditional employee of an organization. To be honest, though, sometimes it's nice to get help. If you're truly on your own, it might be a good idea to find someone to initiate a business relationship with. Human relationships are obviously important. Don't take technology for granted, though. There are plenty of websites and apps that are extremely valuable to freelancers, and I'm not talking about Linkedin, Upwork, or any other job seeking/networking site for freelancers. Here are a few you might not know of.
Quora and Stack Exchange
These two sites are not affiliated with each other, but they both serve the same purpose. With the help of their many active users, you can get answers to almost any questions you have. The only thing you should provide in return is an answer to another question. At quora.com, users ask questions about almost anything, and there's usually a reliable answer offered. Stack Exchange works the same way, but it's geared towards programmers and web designers. If you're not sure about something, just ask!
