losing interest in lucid dreams is the #1 killer of lucid dreamers. We try to stay motivated by staying on DV, watching dream related movies, or relating movies that are not related to dreams to movies. Sometimes it just seems like a waste of time to me even, but it is worth it in the end. Keep trying and keep moving forward. The goal is right around the corner!

Also, 2 weeks without without a lucid is very normal for a beginner. You are doing exceptional for a beginner, keep it up!
