The tutorials make WILDing sound as though you just have to lay down and think about nothing apart from lucid dreaming for about an hour, and you will conciously go into a dream. Is it really that easy?

In every one elses experience, can WILDing be done on the first attempt? I'm going to try it tonight and I want to make sure that I know all I need to know before attempting it. I've had no luck with reality checking, and DILD's.
