Know the feeling mate. When I learnt to fly all them years ago our neighbours used to ask my mum if I was flying at the weekend. If I was they wouldn't hang out their washing or clean their cars as it was guaranteed to pi$$ down!
For the first few months I had something like four out of every five booked lessons cancelled due to naff weather.
Stick with it....brush up on your groundschool when the weather's bad...make the most of the days when you can get airborne.
