I am a bit like you. I've been trying for a few years now, on and off. Finally two days ago, I had my first lucid dream! Just keep at it and you WILL succeed. It's advantageous in life too. An ability that most people don't have. It will give you a new perspective in real life. You can simulate daily encounters in your dreams and improve them. And it's all done in your dreams, so no time is wasted here!
I know it takes time to write dream journals and that could interfere a little bit with life. But hey, people take the time to go to the gym, read a good book etc. This is the same thing. And you can keep your journals short but the most important thing is to never stop. Keep going. Do a little bit everyday.
The world of lucid dreaming has so much potential. No one should have to be motivating you. Explore the dream world. Do extraordinary things. Master your creativity. It's like real life but your imagination, is reality!
