Working as a freelancer, it's important to have a routine, just as you would if you were employed by someone else. Having a routine ensures that you get the job done and meet that deadline, while at the same time continuing the necessity of networking, branching out and working at getting that next project!
Complacency can lead to trouble! You didn't get to where you are today by merely saying, "I think I'll start freelancing." It took time, determination and persistence. Whether you've just begun or have been at this awhile, you've worked hard to get to where you are. Realize that you must continue doing those things - keep that routine - so that you continue to grow, acquire more knowledge, more contacts and more work!
