I completely understand that when you want something *really* badly that the idea of "letting go" can be strange and a lot of people don't explain it very well.  Think of it this way - right now you don't have your desire.  Thus, you need to do something different to bring it about.  "Letting go" means that you are preparing the way for a better result.  You are stepping out of the current moment and into a future where you can actually receive.  "Letting go" doesn't mean you are giving up, it means you are accepting and receiving :D

I hope this helped!
