Well... what kind of product do you want to create?
And what kind of freelance work do you do?
If you don't like what you're doing, then you won't be inspired. Period.
But you can get inspired by doing things that will start moving you in the direction of your goals...and reminding yourself of how this all fits into the bigger plan.
Even if you're not 100% happy doing what you're doing right now... you can start riding that future adrenaline rush if you find a way to intertwine your dreams with your current reality.
(e.g., if you were a freelance writer, you could write an article on how to do something that you really want to do in the next couple months.)
If you start taking active steps to get the ball rolling... then you'll probably start getting excited about the future, and you'll get a rush of creative energy. Try to use that to do whatever you need to do right now.
(And remember: you won't be stuck here forever! You're moving towards something greater...)
