I know this probably isn't the answer you would like, but you need to keep trying. I have been trying too lucid dream on and off for about a year, and the process is pretty straining. Just like anything else you need practice. A lot of practice, and a huge amount of awareness. I didn't really get motivated until I read up on sageous' guide on wilds. I realized that lucid dreaming isn't just control of your dreams, and shouldn't be used for entertainment alone. It's the fact that you are a whole, and conscious no matter what physical state. It's really pleasing knowing that you aren't just doing it to control your dreams, you are doing to know oneself. Anyways I hoped I helped and please don't give up. You would be missing out on the wonderful experience, and the reward is worth the work, and time. Happy dreams
