I have read before that some people claim to actually do activities such as snowboarding in a lucid dream, and the experiences in their dreams actually improved their real life riding abilities. Are things like that actually true? Or is that just a load of bull?

And one other thing, I know this is in the wrong section, but I am a newbie to this. I have tried a few times, but given up after a week or so without success. What should I do to try to induce my first LD?
