Good job, the first cheque is always the hardest to get.
I still have my very first AdSense cheque in my office - never even cashed it. When things don't seem to be going right I drag it out and it gives me a quick reminder that I've done it before, I can do it again (it wasn't even worth 30 euros so I don't feel daft for letting the money slide, the motivation its provided over the years has been more than worth it).
