Pointless getting angry at the inclement UK weather, you will get used to it. But I agree it is somewhat frustrating.
Only my opinion but my advice would be to not worry too much about the cost of ATPL manuals until you have the PPL under your belt and the requisite hours to start. Patience is definitely a virtue in this game!! And yes I do appreciate the fact that the years march on, being a couple of years older than you!!
