I've thought about it, and I've been wondering whether a newbie to LDing could become a master in a week, having 3 - 5 every night.

The only real obstacle I see is belief. Those people (Like Laberge) that can have LDs at will don't have a superior brain, or anything that would make them better than Newbies, except for maybe better dream recall. Having LDs has made me realize the power of our minds, and it's probably far superior than we could ever imagine.

So... could just 100% believing that you're totally capable and willing make you that way?
