The magic bullet seems to be learning to WILD. Depending on your familiarity with meditation, it can be difficult to learn. Once you have it figured out, and have an understanding of how to manipulate your sleep schedule, you can reliably have lucid dreams without too much interruption in your daily life.
I guess it all depends on what you mean by "hard work." Attention all day every day is hard work. Mastering your own mind through meditation is also hard work. Of course, with both kinds of discipline, there are tons of benefits beyond just lucid dreaming.
You may want to try some supplements. There are a few that can make things a lot easier. Galantamine/choline seems to work reliably for me. You still have to figure out how it works, but it takes a lot of the guesswork and luck out of things. I recommend Thomas Yuschak's book if you're interested :
