Write down some specific goals and pick one each night to focus on. It could be something fanciful like flying to the moon or something simple like rubbing your hands to improve clarity. Start simple.

Also, plan and practice a routine to perform as soon as you become lucid. It should include stabilizing the dream, becoming aware of your surroundings, and thinking about the goal you planned to accomplish. With repetition, you will train yourself to think "Ah, I'm dreaming" and then remember to start your routine.
