Hey Tasca, i understand how you feel. It's very hard to keep going when it isn't very fruitful so far.

Try wearing a colored rubber band on your wrist, and reality check everytime you see it. That really helped remind me to do lucid dreaming things during my first few weeks. Also, make a new list of lucid goals every month with specific details on what you want to achieve. It really helps remind your brain that you MUST accomplish it before the deadline, so you get lucid faster. Keep daydreaming, too. I find that repeatedly daydreaming helps a lot to build a storyline and helps your visualization too. To make it a bit better, daydream of something that happens as you go along, and not simply one scene you replay over and over. That way, you'll keeo your interest as to how the story goes next, and you won't get bored easily.

It would also be a good idea to find a lucid buddy on the forums—someone you can talk to regularly and swap stories and attempts with and keep the motivation up. You can even have little contests on doing a certain lucid task, or do experiments and attempts together with him/her so you won't feel bored doing it by yourself and eventually giving up.

Good luck!
