I was very very lucky with my training, but was really helped by being a student at the time, so could fly any time any day, and having an instructor with his own business... who could also fly almost any time and day. Plus the group I learned with weren't that busy, as most people had their own aircraft. As soon as I was ready for the Qx/c, I went on the first good day we had.
BUT I did have to cancel or rearrange many lessons for various reasons. My car broke down, on a roundabout on the way to the airfield (I couldn't just abandon it and hitch to my lesson - too dangerous!). The weather interfered a few times too.
Stick with it and use the time to brush up on your R/T, do some reading, or cadge flights with more experienced pilots.
