I wish I could freelance.
I would love to be able to write, and I'm not even picky about the subject, but I honestly wouldn't even know where to start.
I think it would be a good way to do what I love and make a supplementary income as I'm not too keen on the idea of working fulltime again...
Maybe you should create a schedule for yourself, and try to adhere to it as much as possible. Or at least commit to a set amount of time per day...
That's what I would do anyway.
