On attaining LDs, well I got 6 this week-end (it's easier for me when I can sleep as long as I want in the morning, especially for WILDs), and a few in the week.
My problem is to stay in a LD. I usually wake up only a few seconds after becoming lucid, at best 1 or 2 minutes. Or the LD content dissolves into a black/empty space. I still need to improve my focus/stabilization techniques.
