What is the easiest and most successful way to get lucid?

Every newbie, me included, wants to know this. Which method has the highest success rate? I have tried a few, but none have really worked.
I do R.C.s during the day, have done so for the past 2 days. I also have a 5 week old dream journal.

What method is the best?

(I know there is no best one, but what is the best in your opinion?)
